I want to do mandibular stress analysis and have worked on simulations for Solidworks. but some researchers have advised me to use Ansys as it is dedicated to simulation.
In my perception, Ansys workbench would be better than solidworks. Because the templates for supplying the parameters is easily found in Ansys workbench than Solidworks.
ANSYS is a more detailed software but for beginners, if your analysis is a simple one, SW is more friendly. You may know you can import models from SW (and other software) to ANSYS in case you want to compare the capabilities between these great FEA systems.
