To help understand what the problem<br>is, could someone explain what is meant in the error? Specifically, what it means by "Xth node" of the element. <br>Also, I ran into this issue when I was deforming geometries in the usr file, where one of the elements <br>would overlap another by mistake. However in this case I know there are no overlaps. <br><br>Here is a portion:<br><br> 0 ERROR: Vanishing Jacobian near 91th node of element 69.<br> 1.40692804605498586E-002 -7.79619559165757245E-003<br> 0 xyz: 2.65874E-01 3.54498E-01 2.87050E+00<br> 0 xyz: 2.07855E-01 1.77249E-01 2.87050E+00<br><br><br> 0 ERROR: Vanishing Jacobian near 76th node of element 70.<br> 2.59472856644434001E-002 -2.12442422718029170E-002<br> 0 xyz: 2.11655E-01 4.23310E-01 2.62500E+00<br> 0 xyz: 3.54498E-01 1.77249E-01 2.87050E+00<br><br>Thanks for any help deciphering this error!<br><br>- Michael<br><br><br><br><br><br></div></body></html>
