Re: [DuMuX] Dumux with UMFpack
Hi Ali, SuiteSparse is package of several linear algebra algorithms including UMFPack. They are packaged in different ways depending on the SuiteSparse version and the Linux distribution. 1 ) You can add -lcholmod to the linker line, somewhere near the -lumfpack line. You get the linker line with VERBOSE=1 as mentioned by Bernd. 2) You can try building with static libraries. I haven't done this for a long time, I am not sure whether it works out of the box or what special flags are or avail. 3) Maybe it is worth a try to download the source code and built SuiteSparce. Then the libraries are not oddly chopped by the distribution. I assume this advice will not finally help. If you choose one way and run into further troubles, please report back. Bye Christoph -- The method has been developed for use on a high-speed electronic computer and would be impractical for hand-solution purposes.

[DuMuX] Dumux with UMFpack
Dear Dumux users, I compiled Dumux with UMFpack to run the multi-domain simulations presented by Fetzer et al. 2016 (i.e., Effect of Turbulence and Roughness on Coupled Porous-Medium/Free-Flow Exchange Processes). I got the following errors that I couldn't find any solution for them yet. I would like to know if anyone experienced the same problem and can help me with it.
