I've been frustrated with how FEMAP handles load on faces. Two major gripes:
We are still on v11.2.0 but will soon be on v11.3. Has anyone noticed improvements in this area?
Do not get frustrated, this is the way of running FEMAP, once you are aware of the "philosophy" of FEMAP you will realize that things are in general so easy, and simply, like us!: as a rule of thumb the properties, loads & constraints should be defined or prescribed at the final phase, first you need to get both geometry & mesh density & mesh quality well defined (I play a lot with PLOT-PLANAR elements), and next define properties and prescribe loads & BCs.
Before launching the FE analysis solver you need to revise your FE model, making sure that properties, loads & BCs are correctly defined, not excuses here, activate the HIGHLIGHTER icon, this way when you pick in any property, load or BC the entities are highlighted in the screen, this is an easy way to check your FEMAP model.
Regarding deleting surfaces or faces of solids:
Yo can delete a surface of a 3-D solid, yes, but caution!: this way the solid changes from regular solid to Sheet Solid body, only meshed with 2-D Plate elements.
Of course, I recommend you to install the new version of FEMAP V11.3 as soon as possible, at geometry Parasolid level is much more robust than any previous version, really, really powerful, good job FEMAP guys!.
I understand your perspective, but hope that FEMAP becomes easier to use in the future when it comes to model updates. It should not be so hard to simply delete a face out of a midsurface model.
