Hello everyone,
I'm doing a fem analysis with ansys classic.
when I do the analysis on a simple element, for example a parallelepiped with some hole calculates the solution without problems.
when I use a more refined piece with fitting rays and curved elements, I cannot calculate the solution. in running mesh come out many warnings and some mistakes. when calculating the solution I have errors of this type: ''insufficiently constrained model', ''there are a lot of small pivot terms''. or ''memory pasts''.
Is that a meshing problem? or is the imported model too complex?
or instead should I better set the element type, real constants or constraints themselves?
as element type I used shell 93 and also tried with shell 181.
Thank you.
