The Beauty of Computation
The Logic of Molecules

LiangDong Technology serves universities, research institutes, and innovative pharmaceutical companies with professional technical services spanning quantum chemistry calculations, molecular dynamics simulations, and end-to-end research project support. With rigorous calculation plans and a standardized delivery system, we make every simulation a reliable basis for research.

Core Services

Three pillars covering the full research computing pipeline

From electronic structure to mesoscale dynamics, from one-off computation commissions to long-term project co-development, LiangDong Technology turns complex computational science into research outcomes that are deliverable, reproducible, and publishable.

01

Theoretical Chemistry Calculations

Quantum Chemistry

Based on first-principles quantum mechanics, we solve molecular electronic structures to reveal reaction mechanisms and energy-change patterns, providing microscopic explanations for experimental observations.

  • DFT / Ab Initio structure & energy optimization
  • Transition-state search & reaction-path analysis
  • Spectra, excited states & electronic property prediction

02

Molecular Dynamics Simulations

Molecular Dynamics

Track how a system evolves over time at atomic resolution, capturing conformational changes, diffusion and transport, and interfacial behavior—turning static structures into observable dynamic processes.

  • All-atom / coarse-grained equilibrium simulations
  • Free-energy calculations & enhanced sampling
  • Protein–ligand binding & materials interface analysis

Featured Service · Self-Service Computing

Upload, compute, stay in control

No approval waiting required. From your account you can upload structure files directly, choose the software, method, basis set, and force field, and the system automatically generates standard input files and submits them to the compute queue. Monitor queuing, progress, and result downloads in real time—a truly free and transparent computing platform.

Self-Service Computing

A free computing environment built for researchers. From structure upload to result download, the entire process is under your control, supporting everything from small organic molecules to periodic systems.

  • Supports five major packages: Gaussian / ORCA / VASP / GROMACS / CP2K
  • Compatible with mainstream structure formats: XYZ / PDB / GRO / SDF / MOL2
  • Automatic input-file generation, avoiding manual parameter errors
  • Real-time task status visibility with automatic anomaly alerts
  • Tasks fully isolated with strict data confidentiality
Go to My Account to Try It

Real-Time Progress Monitoring

After submission, tasks automatically enter the compute queue. You can check queue position, submission status, and progress (0–100%) at any time. Anomalies (e.g., non-convergence) trigger instant alerts, and interruption with recomputation is supported.

One-Click Result Download

All outputs are automatically returned upon completion: log files, orbital files, trajectories (.xtc), density cubes (.cube), and more. Full-directory packaged download is supported, so no data is lost.

Strict Data Isolation

Each user's tasks are fully isolated, with data stored in dedicated directories inaccessible to others. After project closure, data is destroyed or archived per the agreed period, and ownership of the results belongs to you.

Rich Method Library

Covers common computation types such as DFT, coupled-cluster, frequency, excited states, molecular dynamics, and solvation models, with preset mainstream basis sets and force fields, while also supporting custom parameters.

Our Advantages

Turning accuracy into certainty

A professional team, stable compute power, standardized processes, and strict confidentiality form the four cornerstones of LiangDong Technology's delivery quality.

01

PhD-Level Technical Team

Core members come from chemistry, materials, physics, and bioinformatics, with years of first-principles and molecular simulation research experience—they understand computation and, more importantly, the logic of research.

02

High-Performance Compute Cluster

A combination of self-built and elastic cloud compute power, supporting CPU/GPU hybrid parallelization and flexible scheduling based on system size, greatly shortening project cycles.

03

Standardized Delivery Process

From plan review and parameter confirmation to mid-term feedback and final acceptance, the entire process is documented, delivering original input files, trajectory data, and a results report.

04

Strict Data Confidentiality

We sign NDAs, store data in isolation with tiered access control; after project closure, data is destroyed or archived per the agreed period, and ownership of research results belongs to the client.

Service Process

A transparent five-step closed loop

Every stage has a clear deliverable and confirmation step, so you always know exactly where your project stands.

1

Requirements Consultation

Understand your research goals, system characteristics, and expected conclusions—clarifying the scientific question rather than merely listing software.

2

Plan Design

Deliver a calculation plan: method selection, basis set / force field, model construction, and compute estimates—launched only after mutual confirmation.

3

Computation

Modeling, parameter optimization, and batch submission, with full monitoring of convergence status and prompt adjustment or recomputation of anomalous tasks.

4

Result Analysis

Data post-processing and mechanism analysis, combined with domain knowledge to produce scientific conclusions ready for publication.

5

Delivery & Acceptance

Submit the analysis report, figures, and raw data, with Q&A support and follow-up supplementary computation provided.

Application Fields

Molecular-scale research across disciplines

Whatever your field, as long as the problem occurs at the molecular level, we can find an appropriate computational path.

Drug Discovery

Molecular docking, virtual screening, druggability assessment

Materials Science

Crystal structures, defects, mechanical & transport properties

Energy & Catalysis

Catalytic mechanisms, active sites, reaction barriers

Chemistry & Chemical Engineering

Reaction pathways, solvation effects, process optimization

Environmental Science

Pollutant adsorption, degradation mechanisms, interfacial processes

Life Sciences

Protein conformations, nucleic-acid systems, biomembrane simulations

Pricing Transparency

Clear cost structure — every yuan spent where it shows

The cost of scientific computing is made up of several quantifiable parts. We list every fee involved so you can estimate the total before commissioning, with no hidden charges.

Computing Core-Hour Fee

Billed by the actual CPU / GPU core-hours a task consumes. Larger systems and more iterations use more core-hours; through scheduling and parallel optimization, every core-hour delivers useful results.

Billed by actual usage

Technical Service Fee (Labor)

Covers scheme design, model building, computation execution & convergence monitoring, post-processing and mechanism analysis. Assessed by project complexity and workload, with a PhD-level team involved throughout.

Assessed per project

Writing Support Fee (Optional)

Paper figure drafting, analysis report writing, grant / project-closing material support. Selected as needed — not bundled into basic computing services.

Optional add-on
Scenario 1

Public Task Marketplace

You can publish a computing task free of charge and set a reference budget (for example ¥1,000). The platform only provides posting, matching and process records: no transaction service fee is charged, and no funds are collected, escrowed or forwarded.

Post a taskFree
Accept a taskFree
Platform service feeNot charged

The reference budget and the actual reward are negotiated and settled directly between publisher and assignee (corporate transfer or contract). The platform does not transfer any funds.

Scenario 2

Commissioned / Self-Service

The total for a commissioned project or self-service computing consists of the following. A scheme assessment and clear quote are provided before work begins:

Computing core-hour fee (actual usage)Billed by usage
Technical service fee (labor)Assessed per project
Writing support fee (optional)Optional add-on

Exact amounts are determined by system size, method complexity and delivery requirements; computing starts only after the quote is confirmed.

Assess first, quote second, start third. All services begin only after the scheme is confirmed and the quote is clear, with no hidden charges beyond the agreed scope; self-service computing lets you view core-hour usage in real time from your account.
