Hi, <\/p>\n

<\/p>\n

I am attempting static structural analysis for shown model with a force on the shortest edge. However i am having difficulty meshing due to the model being very thin. <\/p>\n

<\/p>\n

\"\"<\/p>\n

<\/p>\n

I realised i cannot simply mesh the thin membrane as a 3D body, as errors occur when trying to mesh. I therefore changed to the membrane to a 2D surface in Autodesk Inventor and added thickness in SpaceClaim, which allowed me to create a 1 element thick mesh in Mechanical.<\/p>\n

<\/p>\n

However I now realise i require at least a 2 element thick mesh for the membrane – as warned in ANSYS <\/p>\n

<\/p>\n

“At least one body has been found to have only 1 element in at least 2 directions along with reduced integration.  This situation can lead to invalid results or solver pivot errors.  Consider changing to full integration element control or meshing with more elements.”<\/em><\/p>\n

<\/p>\n

I’d be grateful if somebody could advice me on how to accurately mesh the membrane.<\/strong><\/p>\n

<\/p>\n

I have never used the modelling software in ANSYS such as SpaceClaim or DesignModeller so as much detail as possible would be great, I simply wish to edit my imported geometry from CAD so that I can create an accurate mesh.<\/p>\n

<\/p>\n
