Hi all, I am asking for help again about my computation, that now works fine thanks to you, but slowly. My 2D mesh represents a part that is spinning around a point (0,0). To considerate the centrifugal force, I now calculate the area of each element, and apply a force using "source term brick" on its boundaries. The problem is that add 2000 sources terms for 2000 elements is slow. Do you have any idea of which brick I need to use to set the force in one step ? The centrifugal force is described this way : " F=constant*R " where R is the distance between the rotation point and the element.
To get an idea about my actual code, here it is : Setting all the regions by locating the faces for i = 1:NumberOfElements ftri_rand = get(rot_mesh,'faces from cvid',(i+1)); rot_mesh.set_region(i, ftri_rand); end Applying a force on each region for i = 1: NumberOfElements gf_model_set(md, 'add initialized data', ['VolumicData' num2str(i)], [Fx_tri(i), Fy_tri(i)]./Perimeter(i)); gf_model_set(md, 'add source term brick', mim, 'u', ['VolumicData' num2str(i)], i); end Thank you again for your help, Simon Ameye [cid:image001.png@01D193D3.0D03A420] SIMON AMEYE DQI/DRIA/DSTF/SEPC Apprenti IFP School ________________________________ CENTRE TECHNIQUE VELIZY A /
