Dear all,

Help please! Is anyone working on the mesh movement?
Is the updateCoeff() the only portal to move the mesh points?
Pls correct me if I am wrong:
To use this updateCoeff() portal, one has to provide the delta_displacement to the operator::=.

But sometimes, the delta_displacement is calculated from B-A,
where,
B is the target position, and A is the old position we have now.

But I am wondering if both A and B are small numbers, isn't there going to be an accumulation of the errors?

Any ideas?
