The CL is defined at each Point and dictates the mesh Next we include the electrodes (from Excel file) into the geometryĪnd define the Characteristic Length (CL) for each region and theĮlectrodes.

Mesh can be viewed by running the following lines of code: Meshes of two adjacent regions share nodes on their interfaces. The mesh and assigning region, boundary and electrode markers, the importShapes ( geom_filename )īefore diving into local mesh refinement, putting the electrodes in setNumber ( 'Geometry.OCCScaling', 0.001 ) volumes = gmsh. brep files don't contain info about units, so scaling has to be applied gmsh. add ( 'dike_mod' ) # Load a BREP file (t20.py & demo step_assembly.py) #. setNumber ( 'General.Terminal', 1 ) gmsh. getExampleFile ( 'cad/elec_pos.csv' ) if gmsh : # Starting it up (tutorial t1.py) gmsh. getExampleFile ( 'cad/dike_mod.brep' ) elec_pos_filename = pg.

(3) Select the CompounSolid from the object tree and export (File → Indeed merged correctly to one single compsolid, see the figure Always, also for other geometries.ĬOMPSOLID: 1 and COMPOUND: 0 indicates that the objects were Merged when creating the Boolean Fragments, 3 in this example.ĬOMPSOLID: should be 1. SOLID: in the Shape Content, should match the number of objects Select the newly created CompoundFilter from the object tree andĬlick Check Geometry (Part → Check Geometry). Keep BooleanFragments selected and then apply a Compound Filter to Select the newly created BooleanFragments in the object tree andĬhange its Mode property to CompSolid, see the figure below. 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 modeling 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 modeling and inversion,
