Hi, I'm new to COMSOL and I'm trying to simulate a beam under a load, and I want to study the effects of a increasing load from say, 0 [N] to a 100 [N], I don´t know if I can program a function to increase the force automatically or if I have to do this manually.

In the end I want to get a table that compares the input force to the resulting deflections in the beam

Hi

Select the stationary solver node and expand the "Extension" tab, there you can take a predefined "Parameter" and make it scan a range, and then you multiply your load by the parameter to have it changing

This implies tht you do not change your geometry, only the BCs, otherwise you need to use the "externla" Parametric Sweep functionality

Check the Forum, there are several discussion around this feature

Good luck
