Hello, nI have a problem with my last step in ANSYS - Solution (Solve). Geometry, Mesh is fine, but I still getting error: n nText: An unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes.nAssociation: Project>Model>Static Structural>SolutionnI already tried everything.. nHelp me please. n

Hello Peter,nThanks for the answer. If I look at the file.error here is the message I see:n*** ERROR *** CP = 2.312 TIME= 03:49:12n Thermal strain in element 3802 with material 4 has caused the element n to invert. Please check the thermal expansion definition and the n temperature change. nn *** ERROR *** CP = 2.312 TIME= 03:49:12n Thermal strain in element 5389 with material 4 has caused the element n to invert. Please check the thermal expansion definition and the n temperature change. nn *** ERROR *** CP = 2.312 TIME= 03:49:12n Thermal strain in element 3802 with material 4 has caused the element n to invert.

The matter is if I put the environment temperature and the thermal condition to the same value it works but with results=0 and if I set those two values different it fail. and gives that error message : An unknown error occurred during the resolve operation. Check the resolution output in the Solution object for possible causes.n

ArrayAnsys employees are not allowed to download and review models. So please post pictures in-line with text instead. So, let's start with the simplest mistake that has the largest effect. Double check the material definitions. Perhaps post a screen shot of material '4'. It is easy to accidentally miss the - in the exponent of a thermal expansion coefficient i.e. entering something like 1.7E6 instead of 1.7E-6.nMikenn

Hello thanks for the answer and sorry i did not know. nhere is the list of my material and I think the material 4 is acier standar.nhere is the datails for that materialn

no loguer having that error message when changed the material. But know got this: The preconditioned conjugate gradient solver failed with an error code of 1. Please check for an insufficiently constrained model. Switching to the sparse direct solver may allow this nonlinear analysis to continue beyond this point. nn

nUnder Analysis Settings set the Solver to Direct.n
