Sorry for the cross posting, but I'm a bit new to this.
I have an embarrasingly simple linear static model with a small number of CELAS1 liner springs and forces. It's simple enough to solve by hand. The results for external work, displacements, SPCs, element forces and strains is all fine, but the grid force balance and element strain energies are not. I have grid force balances that are not in equilibrium and strain energy not equal to external work!! There are no DMIG entries and cannot think of any other way I am screwing it up. Surely there isn't anything this simple fundemantally wrong with the code?? Has anybody ever had similar problems?
