Hello,
Basically, I get this error when trying to run a solution in structural
According to the solver output, I got the following problems:
*** ERROR *** CP = 0.984 TIME= 20:46:17
Isotropic material 9 has a value of Poisson's ratio of 3 which must be
greater than 1.0 and less than 0.5 and is therefore not valid for
isotropic materials.
*** ERROR *** CP = 0.984 TIME= 20:46:17
Isotropic material 6 has a value of Poisson's ratio of 290000 which
must be greater than 1.0 and less than 0.5 and is therefore not valid
for isotropic materials.
*** ERROR *** CP = 0.984 TIME= 20:46:17
Isotropic material 5 has a value of Poisson's ratio of 290000 which
must be greater than 1.0 and less than 0.5 and is therefore not valid
for isotropic materials.
*** ERROR *** CP = 0.984 TIME= 20:46:17
Isotropic material 1 has a value of Poisson's ratio of 3 which must be
greater than 1.0 and less than 0.5 and is therefore not valid for
isotropic materials.
*** ERROR *** CP = 0.984 TIME= 20:46:17
Isotropic material 7 has a value of Poisson's ratio of 290000 which
must be greater than 1.0 and less than 0.5 and is therefore not valid
for isotropic materials.

Isotropic material 4 has a value of Poisson's ratio of 290000 which
must be greater than 1.0 and less than 0.5 and is therefore not valid
for isotropic materials.

*** ERROR *** CP = 0.984 TIME= 20:46:17
Isotropic material 2 has a value of Poisson's ratio of 290000 which
must be greater than 1.0 and less than 0.5 and is therefore not valid
for isotropic materials.
*** ERROR *** CP = 1.109 TIME= 20:46:17
The step data was checked and there were errors found.
From what I understood, the materials I imported from SW have impossible Poisson Ratio values, however I set them as 0.29, and not as 290000 as Ansys reported. Any solutions?

What version of ANSYS and SW are you using, maybe this bug was fixed in a newer version of ANSYS/SW.
Regardless of that, you will have to manually edit the materials in ANSYS Engineering Data after import and check each value carefully, making corrections as needed.

However, I managed to fix it by changing the material properties in Engineering Data manually
