Was wondering if there is a way to opt for 2nd order elements in selected regions (face or volume).
This thought came up while doing a simulation with curved thin plate contacting square plates. Want to use 2nd order elements only for the curved thin plate in hopes of keeping number of slave nodes high ( on curved ) so that penetration can be checked. At the moment getting extremely high penetrations at contact.
For reference could go through bonded core- AA8090 >> Run 46.
In the post-processor the curved plate has approx 1.5e-3m displacement where as it is supposed to be around 3e-3m ( which is the displacement of the rigid plate pushing down, also the master here) if contact compatibility is met.
Probe for displacement at contact point (approx) of curved plate (slave)
Probe for displacement at contact point (approx) of rigid plate.
Also wanted to know whether option of giving different mesh max element edge length is possible for different parts. Trying to keep the master mesh coarser than the slave. Currently while applying region refinement in the slave faces, the mesh of the master close to this slave face also gets refined. Is it possible to get the master mesh coarser than the slave mesh
