Most useful freecad macros code#
If the macro doesn’t start, and you have an error like No module named 'gui', try to close and restart FreeCAD after making sure the macro and the code are at the right place. To start the case, simply click on the execute macro button, and select FemCloudComputingQarnot.FCmacro. You can now close the tab displaying the macro code. For example, if the console outputs, '/usr/local/lib/python3.8/dist-packages/qarnot/_init_.py', the line (1, '/usr/local/lib/python3.8/dist-packages') should be added. Then, in the macro, below the first line, add a second one with the printed path to the SDK. To do that, open a standard python console and execute
If you are using version 0.19.3 or after, you will also need to tell FreeCAD where you installed qarnot sdk. For example, on my computer it would be (1, '/home/alexis/.FreeCAD/Macro/qarnot-freecad-plugin') In FreeCAD, click the execute macro button, select, FemCloudComputingQarnot.FCmacro and click edit on the right.Įdit the line (1, '*******') by changing the stars to the folder in which the code was downloaded. If the macro code is in a subfolder of the Macro folder, do the following :Ĭopy the FemCloudComputingQarnot.FCmacro file in the macro folder Its location can be seen at the bottom of the macro selection window opened by the execute macro button (see below).

Go to the macro’s GitHub, and clone or download the code in your macro folder. If you downloaded the binaries, go to Edit -> Preferences -> FEM, select Elmer and fill in the path to the two Elmer binaries ( ElmerGrid and ElmerSolver).

Download the binaries or install them with apt-get if you are a linux user. If you want to use Elmer, you will need to install it as well. Select Gmsh tab and fill in the path to the Gmsh binaries (for exemple /home/gmsh-4.8.4-Linu圆4/bin/gmsh) Open FreeCAD and go to the FEM workbench, then to Edit -> Preferences -> FEM. Run gmsh to make sure it is correctly installed. If you are a Linux user, make sure to download the last version instead of using, apt-get which installs a deprecated version. Versions previous to 4.8.0 may cause some error. AppImage is downloaded, use the command chmod +x FreeCAD_0.19****.AppImage to make it an executable.ĭownload Gmsh binaries and unzip it somewhere. Install the last version of FreeCAD from its website. You will also need FreeCAD with Gmsh installed and the macro. Install Python SDK with the command pip install qarnot. Make sure you fulfill Qarnot prerequisites before launching the case : If you are interested in another version or another solver, please email us at Prerequisites The macro currently supports the following solvers : It also makes it possible to send several simulations at once or let a simulation run overnight while the computer is shutdown. Qarnot’s plugin makes it possible to send FEM computation on Qarnot’s platform, hence making you save time and computer power. The FEM workbench from FreeCAD integrates these solvers inside FreeCAD, which makes it possible to use its modelling capabilities within a unified GUI. Most useful freecad macros free#
Many solvers, including free and open-source ones, implement this method. It can even be used to perform fluid dynamics simulations and to resolve multiphysics problems. The finite element method is the most widely used numerical method to perform physical simulations in fields like mechanics, heat science or electrostatic. Thanks to its active community, it also has many features integrated, including a module to perform finite element analysis.
FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size.
