constraint controls, no checks
constraint controls, no checks
(OP)
Hello everyone,
I am trying to model a quarter RVE UD composite and calculate it's efective properties
Due to the tie constraint i use for the interface plus the axisymetric contrains in the three faces of the cube i get an overconstraint warning when i run the model which however doesnt affect the solution, but when i increase the mesh i get this warning message:
VERCONSTRAINT CHECKS: THERE ARE 21195 BOUNDARY CONDITIONS SPECIFIED IN THIS MODEL. OVERCONSTRAINT CHECKS FOR BOUNDARY CONDITIONS SPECIFIED ON SLAVE NODES OF RIGID BODIES, OF *TIE OPTIONS, OR OF *COUPLING OPTIONS REQUIRE 8 Mb OF MEMORY. IF THIS IS A PROBLEM, PLEASE TURN OFF OVERCONSTRAINT CHECKS USING *CONSTRAINT CONTROLS, NO CHECKS or INCREASE THE MEMORY USED BY THE PRE-PROCESSOR.
I need to disable constrain controls graficaly however because i need the .jnl file with all the comands to build a python script for parameterization can anyone help me find where this option is?
Thanks in advance

RE: constraint controls, no checks
Why don't you take out the regions that are overconstraint from the tie or boundary?

With that is is easily possible to avoid overconstraints.
