Hi
If the logical structure (not actual values) of the matrix remains same, is there a way to avoid symbolic factorization stage for problems requiring large number of of linear system solutions?

you may set maxfct ( maximum #of factors with identical sparsity structure) accordingly your case, make symbolic factorizations only once and then do numerical factorization maxfct times. we have a couple of examples show these cases.
Could you please direct me to an example to achieve this?
My problem involve solving many linear systems (to obtain solution to non linear system)
For example, I would like to solve
A1 x1 = b1
then
A2 x2 = b2
where A2 depends on x1, but the sparsity of A1 and A2 are the same (however I do not have A2 until I solve for x1)
