Hi,
Have a look at the following example -
https://www.mathworks.com/help/pde/examples/deflection-analysis-of-a-bracket.html
In this example, a bracket has been imported as a STL file and then FEA analysis has been done to find out the deflection under load. This will give you idea for the complete workflow.
Regards,
Abhisek

hello Abhisek,
This function doesn't work for me because my .stl model is in a ribbon shape which has only two faces. so i get the next error !
__________________________________________________________________________
Error using pde.DiscreteGeometry Failed to create geometry, the input does not form a closed volume. This may be due to missing faces or gaps in the input.
Error in pde.PDEModel/importGeometry (line 51) gm = pde.DiscreteGeometry(geofilename);
__________________________________________________________________________
any other suggestions ? and if i can mesh it, can i extract the data points in (x,y,z)? Thank you.
