If there can be substantial relative motion between the primary and secondary surfaces during the nonlinear iterations within a timestep, it is advisable to use 'iteration' option to ensure accurate contact detection.

CHANGING MESH ORIENTATION IN GMSH PATCH

'auto' will attempt to determine at the start of which timesteps the patch for all secondary nodes needs to be updated automatically.'iteration' updates the patch at every nonlinear iteration for a subset of secondary nodes for which penetration is not detected.

CHANGING MESH ORIENTATION IN GMSH UPDATE

'always' will update the patch for all secondary nodes at the beginning of every timestep which might be time consuming. The default is to never update it (which is the most efficient but could be a problem with lots of relative motion). Now, we are going to build the box.Description:How often to update the geometric search 'patch'. A handy way to set the same mesh size to every Point is to use the two commands Mesh.CharacteristicLengthMin and Mesh.CharacteristicLengthMax at the beginning of the file : SetFactory('OpenCASCADE') The mesh size must however still be set on every Point. With this engine, you generally do not have to build the Point by hand, as ready-to-use geometries are provided. This command forces GMSH to use OpenCascade engine instead of the native one. Open a new file, box.geo, and copy/paste the following line on top of the file: SetFactory('OpenCASCADE')
