Hi all friends.

In order to solve my equations in coupled approach, I have implemented a new linear solver (in OF 2.2.0) for solving LduMatrix<Type, Dtype, LUType> equation system. Both my linear solver and application solver are compiled and made without problem. But when I run my case (cavity), it terminates with this strange error!

...

Starting time loop

Time = 1

Segmentation fault

I know this error corresponds to lines I introduced the linear solver by New function, but I don't understand what it really means! Would you please give me some guidance to find where my fault is?!

Any kind of information would be added, if necessary.

Thanks.
