hi to all I am new to the forum and I apologize for the mistakes I will make in posting the messages.
I have always followed this forum from outside, but now I have enrolled and I try to be an active part entirely. I am currently dealing with the validation of a fem calculation on a set of an injection mould. I used for modeling cad solidworks, pre/post nastran fx and as innastran solutor. I set a linear analysis with linearized contacts using a mesh for some components (those + complex, mainly the three floors of the press) to tetra and for those "mappabili" to hexa. the results obtained from the fem and those detected with strain gauges however differ in some points also by 25%. That's how I was doubtful about the correctness of using some hexa and others in the same model. according to you can affect the result in terms of different stiffnesses and then "falsed" values use different type elements in the same model?
thank you in advance for the answer.
greetings
