<div dir="ltr"><div><div>Hi there,<br><br></div>I have a tetrahedral mesh I created with extrude, from a triangular base, in a .geo file. At the moment the domain is rectangular.<br> <br>Does anyone know if there is a way in GMSH to set the thickness and surface elevation to vary. In this case, the surface elevation to vary sinusoidally as given by a certain function and a constant slope in the thickness as given by a function. <br>
<br>I know there is MathEval - I was wondering if / how this can be used with the tetrahedral mesh I created with extrude, so that the thickness and surface elevation vary. <br></div><div>Thanks,<br></div><div><br></div>Jonathan<br>
