26.05.2015 · Hello, I'm using ANSYS workbench 15 to simulate thermo-electric analysis. I'm using 2D axis-symetric in order to reduce time calculations. The problem
May 27, 2015 · Also check that your mesh has more than 1 element in at least 2 directions if solid brick elements are present. Please see the Troubleshooting section of the Help System for more information. I tried searching for a solution for this problem but didn't succeed.
23.09.2008 · Preconditioned conjugate gradient solver error level 1. Possibly, the model is unconstrained or additional iterations may be needed. Try running with a multiplier MULT > 1 in EQSLV command (3 > MULT > 1). but the only way is to constrain it (all DOF = 0) in both sides where pretension is acting... : ( Thanks, Lukasz

Leave the Minimum Substeps at 1. Set the Maximum Substeps to 200. If the above is insufficient to achieve convergence, change the Solver to Direct.
Memory usage permitting, convergence of the Picard iteration might also be aided if fill level IFILL = 1 can be used. If any of these modes produce a Picard ...

Initial penetration 0 was detected between contact element 112650. and target element 112721. Max. Initial penetration 0.475991245 was detected between contact.
Sep 13, 2007 · In order to use this model the USERMAT subroutine has been edited and successfully implemented in ANSYS mechanical environment. when I run the simulation using the iterative solver type I receive the following error: The PCG solver detects that the stiffness matrix is ill-conditioned. The solution has not converged.
