Meshin of a multiple thin layer "Sandwich" construction
im modelling a "Sandwich-Plate" of different materials. There are 7 Layers from between 1.5mm to 0.075mm in thickness. I reduced the Surface are with 2 Symmetries, but the plate is still 500mm x 700mm. The idea is to modell the bending of the plate from Temperature change and the different thermal expansion coefficients. Therefor i use a static thermal with a static structural to measure fore and deformation.
The problem i have, is that the Meshing creates a lot of Elements and my system cant handle the load or it just takes days tot calculate. The Mesh size i want to have is round 10x the thickness, i controll the Mesh size with "Mesh size" for every layer separately. Because the surface area is so big, it creates a lot of elements on the surface when i Mesh the 0.075m layer. Also i still have only 1 Elements in Z-axis (thickness), but is so thin that i guess its okay to have only 1?
I saw in other disscussion that i could use Shell Elements. However i still get too many Elements. Does anybody have experiences in Modelling a multiple layer board, that has bog surface area, with very thin layers?
Thank you for your help, this is my first post and im not very competent in Ansys workbench either. So if you need any more Infos to help me, please let me know.
