Title: UMFPACK for FEAPpv
Post by: ash_jam on August 08, 2021, 08:58:49 PM

Hello sir,
Thank you very much for distributing FEAPpv as opensource.
How can we interface new solvers like UMFPACK to FEAPpv ?
Moreover - how can we understand the control flow in the program ? How the commands are being executed... ? Is there any reference ?

Thank you,
Ash

FEAPpv has a user solver interface.  So if you take the published files that work with FEAP you should be able to make them work with FEAPpv (perhaps with a bit of adjustment).

Regarding the execution process of FEAPpv, you can try looking in the 4th (?) edition of Zienkiewicz and Taylor, which I think has a brief description of the program flow; the 5th and later editions should also have a similar chapter.

Thank you sir.
It is available in 5th edition - I could get that in library. Now I am able to go through.
Why this valuable information was not printed in subsequent editions ?
