The load is a pressure applied to surface elements in order to simulate a kind of wind- load. It is constant over time, but will change by the deformation of the sail (only the normal components are taken, not the tangential ones).
Hi everybody,
yesterday a meeting with my mentor took place, and we considered the ridig body motion as the main problem. Because there are no displacements constraints set, the LMM would not be possible.
My next thougt was to avoid working in a moving coordinate system trough moving the...
Hi and thx for your replies,
to Drej:
I should have known about getting the velocities and acceleration by a derivation. Thx for the tip
About the LMM:
Am I right if I would connect every node of my solar sail with a Large mass and apply the equivalent Forces equal to nodal acceleration...
Hello everybody,
im simulating the flight of a solar sail (highly nonlinear) with ANSYS and get VERY large displacements which cause the nonlinear transient Iteration to fail.
Thats why i want to move the coordinate system every n-th step.
So I have to restart the analysis using the...
