Launching error

MFiX Installation
#1

Hi,

I just installed mfix and tried launching it. But it showed me this error. What should I do now? Thanks for your help!

Traceback (most recent call last):

Hi @Ashin_Sunny , welcome to MFiX

I haven’t seen this error before. But we are releasing a new version, 21.2, very soon. It hasn’t been announced yet, but if you do
conda deactivate
then repeat the installation command with all of the 21.1.4’s replaced by 21.2, and -c mfix replaced by -c conda-forge you will be able to do a test installation of the new version. That is, the installation command should look like

conda create -n mfix-21.2 mfix=21.2 mfix-doc=21.2 mfix-gui=21.2 mfix-solver=21.2 mfix-src=21.2 -c conda-forge -c  https://mfix.netl.doe.gov/SECRET_TOKEN

I’d be very interested to know if the 21.2 version also has this DLL load failed issue.

Hi Charles,

For now, I have installed a previous version and it is working. I will let you know if have the same error when I install the latest version in the future.

Thanks,
Ashin
