Applying nodal displcaments from one mesh to another

Applying nodal displcaments from one mesh to another

Applying nodal displcaments from one mesh to another

(OP)
Hi Guys,

I have two mesh models, one in a reference unloaded geometry  and the other in a loaded geometry.

I want to add a further part to these meshed models such that i can look at the stress on this part due to the deformation of the previous meshed part.  

However the problem i have is that i do not know the B.C's allplied to the unloaded geometry to make it into the shape of the loaded geometry. I simply just have a mesh of the unloaded and loaded cases.  I extracted the nodal coordinates from both the unloaded and loaded meshes.

If i want to run  dynamically run the model it will mean applying the difference in displacement at each node to the unloaded model, however there are approx 60, 000 nodes so this is not possible! Anybody have any faster method or ideas?  

Any help would be much appreciated!!!
