Mesh movement accumulation error???
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? |
