[CIG-MC] ConMan issues report

Wed Aug 17 15:35:37 PDT 2016

Dear John

If you are running on a mac, more testing/debugging may be required.

Yes, we're running on a mac. I can try running on a linux if it's simpler, but what is the testing/debugging that is required?

A bit off topic, but is there a particular reason you choose ConMan?  ASPECT might be a better choice if you would like to run in parallel, do 3D simulations, use adaptive mesh refinement, etc. There is nothing you can do ConMan that cannot be  easily duplicated in ASPECT.  Happy to help you get setup with ASPECT if you would like to try it out.

Hm, interesting. We are in fact building our own code for specific problems in icy moons, and want to benchmark the code. We can get the isoviscous Blankenbach tests right, but we're running into some problems for variable viscosity (cases 2 and 3). We want to check the output of a code that does these cases right to see where we're doing wrong.

Did you benchmark ASPECT against the Blankenbach problems as well?

Cheers,

Wlad

Dear Leondardo,

There is indeed an issue with the GitHub version of ConMan, thank you for the reminder ;)

We will push a patch to github in the next few days and let you know when it is ready to download and install.

On your end, what operating system are you trying to install ConMan on?  The updated version of ConMan should compile and run successfully on linux if you use the gfortran64 compiler and associated Makefile.

The code does compile successfully with the 32-bit compiler, but will crash upon execution.  This seems consistent with your error?

If you are running on a mac, more testing/debugging may be required.

A bit off topic, but is there a particular reason you choose ConMan?  ASPECT might be a better choice if you would like to run in parallel, do 3D simulations, use adaptive mesh refinement, etc.

Anyhow, we will get ConMan updated in the next day or two.

Cheers,
John

Dear ConMan developers and maintainers,

I am writing on mine and Professor Wladimir Lyra’s behalf, currently researching on icy convection.

We downloaded and installed ConMan from both the git repository conman.git and via the direct tar link https://geodynamics.org/cig/software/conman/ConMan-2.0.0.tar.gz<https://urldefense.proofpoint.com/v2/url?u=https-3A__geodynamics.org_cig_software_conman_ConMan-2D2.0.0.tar.gz&d=DQMFaQ&c=Oo8bPJf7k7r_cPTz1JF7vEiFxvFRfQtp-j14fFwh71U&r=betAI_WKi5c6efJqRXXEeDH07uoTxe7Vp010C6-tIlg&m=-SjoKD3I2cgpC0-lR2OFWlbaIaO4ml-VdNEZ7nzJf4E&s=x9fwriz_-ajoIC28JmsCNTLf3nT679rikpXcvR-YamI&e=>. However, both ways gave us issues that I would like to address here:

1- When installing via the git repository, the src directory lacks the libs folder, which we had to take from the installation via tar in order to compile.

2- After compiling (using the git repository installation + libs folder from tar), we could not run the code by following the instructions. Here is the output of our trial:

:~/ConMan/conman/cookbook1$ ../src/conman.pic < run.bb1a50
Segmentation fault (core dumped)

We are either missing something or there is an installation problem that we alone cannot solve. I hope this report helps the ConMan team to make the code even better. We appreciate any attention given to this case.

Thanks in advance,
Leonardo S. Cassara
