Internal Force

After solving the Model, TriangleElements will have some internal forces. Internal force at each location of element can be different and it can be catched with method TriangleElement.GetInternalForce. with get the location that you need the internal force as input. Internal force means membrane and bending tensors which are shown in picture: TODO show with returned axis directions

Note that value returned from this method is in element’s local coordination system. to convert to global system: TODO
