With solid element, constraint 1 node is not enough.

Yes, it is unneccesary. We can even select inside without masking/exploding/X-section.

Did you confirm unit of force and material parameters?

It just detects holes but not bolts. You need a script to detect bolts. A simple case of bolt has 'hexagon head' that you can use to detect.

Could you share *.fem file? Can you estimate displacement theorically?

Could you show your geometry? Use 'mask' panel to be able to view inside a part

If you constraint 6 dofs of solid element you will see a warning message says that it affects to only 3 dofs. If nodes are shared among solid elem and shell/beam elem, it will affects to 6 dofs. Hypermesh is designed that in order to be useful in many situations.

Use "wm withdraw ." in your script

Hi Did you tr *createmark surfs 1 "by adjacent" ?

Yes, it is. Write a simple tcl script to do it.

Maybe... a bug! New version usually comes with bugs.

Cannot reflect a ref system because its x,y,z will be changed from right hand rule to left hand rule

Hyperview should have an option to plot them in resolved system. Or you have to try creating derived results before plotting

If you dont figure out. Make a simple problem to check it

Reasons might be you calculate wrong or hypermesh calculates wrong or optistruct calculates wrong
