Geometry and mesh

Use these guides to change where fluid and solids exist, place conditions on their surfaces, and check that the mesh preserves the features that matter.

• Set the computational domain around the relevant fluid paths and components.
• Add a cuboid component when an axis-aligned box is an adequate representation.
• Add a thermal interface layer to represent a thin layer’s resistance without meshing its thickness.
• Build an assembly from cuboids for enclosures, fins, plates, and channels.
• Add a CAD component from a STEP or STL file.
• Select a boundary region on the exterior domain or an insulating cuboid.
• Configure the mesh to control cell sizes, retain important geometry, and reduce unnecessary cells.
• CAD voxelization explains how imported surfaces become solid cells and which geometric details the mesh can retain.
• Reduce a model with symmetry to mesh one half of a mirror-symmetric problem.
