NovaSolver Studio

Studio 0.5 adds structural modal analysis, uniform or solved-temperature thermal stress, gravity and centrifugal loads, and moment, bearing and remote-force face conditions. Six examples compare the computed answer with a closed-form reference: cantilever-modal, thermal-bar-fixed, thermal-bar-free, hanging-bar, rotating-disk and shaft-torsion. Structural studies track maximum displacement; modal studies track the first elastic frequency. Results include section caps, click probing, mode animation and a line chart with CSV download. The results Export menu and MCP export_results tool write ParaView VTU, CSV or a self-contained printable HTML report into the case's exports folder. From the CLI: python -m novastudio export-results CASE_ID vtu (also csv or report).

Open-source engineering simulation you can trust — structural, thermal and flow — operable by you or by your AI assistant. 構造・熱・流れを解く、オープンソースの解析ソフト。画面からも、AI アシスタント（MCP）からも操作できます。

Early preview (v0.x). Every result comes with a clear status: ran → converged → verified. 開発中のプレビュー版です。結果には常に「実行できた → 収束した → 検証済み」の判定がつきます。

What it does / できること

Analysis	Geometry	Quick preview (built-in, seconds)	Final solve	Verification
Structural (linear static)	templates · import STEP / IGES / BREP	quadratic tetrahedral FEM	CalculiX	beam theory, Heywood Kt, mesh convergence (GCI)
Thermal (steady conduction)	templates · import	quadratic tetrahedral FEM	CalculiX	Fourier's law, fin theory, GCI
Internal flow	templates · import	2D cavity (built-in)	OpenFOAM®	Ghia (cavity), Poiseuille, mass balance
Flow around a body	import	—	OpenFOAM® (snappyHexMesh + wall layers)	sphere drag vs Schiller–Naumann (+0.3%)
Water cooling (conjugate heat transfer)	import (2+ bodies)	—	OpenFOAM® (chtMultiRegionSimpleFoam)	heat balance (0.03%)

Verified, not just "it ran" — every template is checked against an analytic or literature reference; imported shapes are checked by an automatic mesh-convergence study (Roache GCI).
Warnings that matter — e.g. stress above yield: the linear result does not hold, even if "verified".
Japanese / English / Chinese UI, light & dark.
MCP server with typed tools: create or import a case, set conditions, run, check convergence, verify, render. No shell or code-execution tool. Your AI's edits appear live in the GUI.

Install with Python (macOS / Linux / Windows)

macOS / Linux (preview, community-tested).

After the first PyPI release, launch the GUI with uvx novasolver-studio, or install once with pipx install novasolver-studio and run novasolver-studio. Python 3.10+ is required; Python 3.12 is tested in CI. Older Python versions use compatible NumPy/SciPy/Matplotlib/WebSocket releases. The built-in FEM needs no external solver. For an MCP client:

{
  "mcpServers": {
    "novasolver-studio": {
      "command": "uvx",
      "args": ["novasolver-studio", "mcp"]
    }
  }
}

With pipx, use "command": "novasolver-studio", "args": ["mcp"] instead. Cases go to ~/NovaSolverStudio/workspace on macOS/Linux and ~/Documents/NovaSolverStudio/workspace on Windows; NOVASTUDIO_WORKSPACE overrides this. Source checkouts keep their workspace/ folder.

OS	CalculiX (optional structural/thermal solver)	OpenFOAM (optional CFD solver)
macOS	`brew install costerwi/calculix/calculix-ccx`	`brew install gerlero/openfoam/openfoam` (Apple Silicon, macOS 14+)
Linux	`sudo apt install calculix-ccx` or the distro package	Install ESI packages from openfoam.com; detected under `/usr/lib/openfoam` or via `WM_PROJECT_DIR`.
Windows	Put `ccx_static.exe` in `solvers/calculix/` or set `NOVASTUDIO_CCX`.	ESI Windows MinGW build plus Microsoft MPI, as described below.

On headless Linux, Gmsh needs libglu1-mesa libgl1 libxrender1 libxcursor1 libxft2 libxinerama1. NOVASTUDIO_CCX and NOVASTUDIO_OPENFOAM can select an installation on every OS. macOS OpenFOAM tools run through the app environment launcher; Linux tools source the installation's etc/bashrc.

Quick start (developers) / 開発者向けの起動手順

python -m venv .venv
.venv\Scripts\python -m pip install "mcp>=2.3,<3" fastapi "uvicorn[standard]" numpy scipy matplotlib gmsh meshio psutil pyamg pymeshlab zstandard pytest
cd frontend && npm install && npm run build && cd ..
cd backend
set PYTHONPATH=%CD%
..\.venv\Scripts\python -m novastudio serve        # open http://127.0.0.1:8765

Solvers are found automatically when installed (without them, the built-in preview solvers still work):

CalculiX: put ccx_static.exe under solvers/calculix/ or set NOVASTUDIO_CCX.
OpenFOAM (ESI Windows MinGW build): install to %LOCALAPPDATA%\NovaSolverStudio\solvers\openfoam (an ASCII-only path) or set NOVASTUDIO_OPENFOAM. Put Microsoft MPI's msmpi.dll in %LOCALAPPDATA%\NovaSolverStudio\solvers\msmpi.

Use it from an AI assistant (MCP) / AI アシスタントから使う

Easiest (Claude Desktop and other MCPB-aware apps): download novasolver-studio-<version>-win64.mcpb from Releases and open it — the app installs it as an extension. Also listed in the MCP Registry as io.github.novasolver/novasolver-studio.

With the downloaded zip: point any MCP client at the exe.

{
  "mcpServers": {
    "novasolver-studio": {
      "command": "C:\\path\\to\\NovaSolverStudio\\NovaSolverStudio.exe",
      "args": ["mcp"]
    }
  }
}

From source:

{
  "mcpServers": {
    "novasolver-studio": {
      "command": "<studio>\\.venv\\Scripts\\python.exe",
      "args": ["-m", "novastudio", "mcp"],
      "env": { "PYTHONPATH": "<studio>\\backend" }
    }
  }
}

Then ask, for example: "Import bracket.step, fix the bottom face, push 500 N on the top face, run it and tell me whether the result is verified."

Electromagnetics (0.3) / 電磁気

The built-in tet10 solver now computes electrostatic potential, electric field and electrode charge, or DC current with optional steady Joule heating. STEP assemblies can assign a dielectric or conductor to each body. Three editable templates include analytic checks: capacitor against εA/d, coax against 2πεL/ln(b/a), and busbar against L/(σA) and the temperature rise σΔV²/(8k) with both ends cooled.

内蔵 FEM で静電場・電流・ジュール発熱による温度を計算できます。平行平板コンデンサ・同軸ケーブル・銅母線の 3 テンプレートには解析解との比較があり、任意形状ではメッシュ収束を確認できます。

Share face selection with an AI (0.4) / 選んだ面をAIと共有する

Select faces in the boundaries viewport, then ask “fix the faces I selected” or “put 500 N here”. The assistant reads get_gui_selection, shows a numbered render_view(quantity="faces", highlight=[...]) to confirm the setup, and applies conditions through update_case. GUI and AI changes share one Undo/Redo history. Ctrl+Z undoes the latest change by either of you; Ctrl+Shift+Z or Ctrl+Y redoes it. Named face groups can be reused with boundaries.@<group>.role and other boundary fields.

画面で面を選んでから「選んだ面を固定して」のように頼めます。AIが選択内容を読み取り、面番号付きの画像で確認してから条件を設定します。画面とAIの変更は共通の履歴に残り、どちらの変更も元に戻せます。 Hで選択した面を隠し、Alt+Hですべて表示。Ctrl+ドラッグで矩形選択、Xで透過表示を切り替えます。

在视图中选择面后，可以说“固定我选中的面”。AI会读取选择内容，用带面编号的图片确认设置，再应用边界条件。界面与AI共用撤销和重做历史，双方的更改都可以撤销。面组可以保存并重复使用。
