In the Part workbench, select all objects and create Booleanįragments (Part → Split → Boolean Fragments) ![]() Open a new project and merge all objects, i.e. (2) The trick then lies in merging these shapes into a singleĬompsolid. The sandĬhannel is a simple cube, created in the Part workbench. FCStd FreeCAD files and playing around with them. You can also have a look at how these geometries See the Inversion-Region in the object tree In the Part Design workbench, by making a sketch and then extruding (1) The outer and inversion regions of this dike example were created Meaning one object that consists of multiple solids that Merge all regions into one single ”compsolid”, i.e.composite To get familiar with the part design workbench, this Workbench, or in the Part Design workbench for more complicated The geometries are defined in three steps:Įach region of the geometry designed separately in the Part Regions: the outer region and the inversion region. Outer region the inner region (same as inversion region in thisĮxample) and the sand channel. The modelling geometry consists of three regions: the Therefore, the mesh itself would act as prior information The geometry of the sand channel is alreadyincluded in the structure When the same meshes are used for modelling and inversion, The target in this example is to find the geometry However, this FreeCAD → Gmsh workflow can easily be This example is based on an ERT modelling and inversion experiment on a In case you also want to try out FreeCAD, installing it from their Here’s the last part of that gigantic error message: h5py/h5a.pyx:184:36: Cannot convert 'void *' to Python objectįile "/tmp/pip-install-m_w5y09w/h5py/setup.py", line 159, in įile "/usr/local/lib/python3.6/dist-packages/setuptools/_init_.py", line 145, in setupįile "/usr/lib/python3.6/distutils/core.py", line 148, in setupįile "/usr/lib/python3.6/distutils/dist.py", line 955, in run_commandsįile "/usr/lib/python3.6/distutils/dist.py", line 974, in run_commandįile "/usr/local/lib/python3.6/dist-packages/setuptools/command/install.py", line 61, in runįile "/usr/lib/python3.6/distutils/command/install.py", line 589, in runįile "/usr/lib/python3.6/distutils/cmd.py", line 313, in run_commandįile "/usr/lib/python3.6/distutils/command/build.py", line 135, in runįile "/tmp/pip-install-m_w5y09w/h5py/setup_build.py", line 209, in runįile "/tmp/pip-install-m_w5y09w/h5py/.eggs/Cython-3.0a3-p圓.Conda install -c conda-forge gmsh python-gmsh After uninstalling meshio and h5py, reinstalling them using the above comands yield a gigantic error message for the h5py package. I would like to point out that this answer doesn’t work for me.
