MAX_NUM_DOF in TransformationFE.cpp

[weiquanli]

Dear OpenSEES Community members

I implement a special element in OpenSees, and it consists of more than 200 nodes. When I set up a model,I must use the command "constraints Transformation". I found that the "MAX_NUM_DOF" in TransformationFE class(TransformationFE.cpp)
was set as 64,which brought about a bug. So I set the "MAX_NUM_DOF" as 200 and the program runs successfully, but the memory runs out and error occurs.

I would like to ask what impact the variable "MAX_NUM_DOF" has on the whole class ? Will it bring out memory problems?

Thank you

how large is the model? .. it is playing with matrices of size 200x200 or about 3MB for each element matrix .. if you are inefficient in the storage or you have a lot of ele you are going to run into memory problems.
