Jens, thank you !

I took a close look at the manual and I know now, where be matrix A.

But I have new questions.

1. How I can choose suitable solver ?

Why you ask about GMRES ? Believe you GMRES is better than BiCG ?

2. How I can choose suitable preconditioner ?

3. How I must correctly choose and arrange statements in the solvers-loop ?

Must they be arrange exactly as in example in manual ?

Exist here some consideration ?

Regards. Juri Ivlev.
