I have imported an stl file of a propeller from Solidworks to Matlab. I want to apply the Gaussian Distribution equation, plume model, to find out the new mass and center of mass of the propeller after some time "t". I'm hoping to have the plume model distribute over the top face of the propeller. I'm thinking that I will need for loops to run this equation over every point of the trimesh from the stl file, so Im wondering how I can access the x,y,and z components of the trimesh to use them as parameters in the for loop to apply this distribution over a 3d object or at least over its top face.
