I want to understand the meaning of this statement 'RBE3 with less than 3 legs should not exist '.
I am defining seam welds with hexa adhesive type (RBE3-HEXA-RBE3). How to avoid the 3 legs in RBE3 type of connection?
Thanks in advance.
'RBE3 with less than 3 legs should not exist '
It means for single RBE3 element you should not have less than 3 slave nodes.In your case RBE3 which has two slave nodes is creating problem for run.
Hi,
Looks like your mesh size is coarse or try increasing tolerance so rbe3 will cover more nodes
Hi, Looks like your mesh size is coarse or try increasing tolerance so rbe3 will cover more nodes
But how do I check those rbe3 with less than 3 legs? There are nearly 5000 rbe3 in my model. Do I need to check them individually?
a few tcl commands can help you to filter them:
*createmark elems 1 'by config' rbe3 *createmark elems 2 'less than value' nodecount 4; # 2-leg rbe3 has 3 nodes *markintersection elems 1 elems 2 *entityset[expr [hm_entityinfo exist sets <3-legRBE3 -byname]?'update':'create'] <3-legRBE3 elems 1 *clearmark elems 1 *clearmark elems 2
above will create a set of concerned rbe3 so you can review them
