19.3.1 installation issues

Hello Team, I’m trying to installing MFiX-19.3.1 on Ubuntu and facing the attached error.

I first downloaded Anaconda3-2021.05-Linux-x86_64.sh and issued bash Anaconda3-2021.05-Linux-x86_64.sh to install this package. After this, opened a new terminal and copy-pasted conda create -n mfix-19.3.1 mfix=19.3.1 mfix-doc=19.3.1 mfix-gui=19.3.1 mfix-solver=19.3.1 mfix-src=19.3.1 -c mfix -c https://mfix.netl.doe.gov/s3/3e2b2dcf/a0176e4dfc12d7480bdfa03abb5d1617/conda/dist from MFiX webpage.

When I open the GUI using conda activate mfix-19.3.1, I get this error on the screen.

Could not import VTK, please check your installation.

How to troubleshoot this? Thank you.

Looks like you are missing libtbb.so.2. What version of ubuntu are you running?

I don’t have an Ubuntu image atm, but does this work?

sudo apt install libtbb

Hello @onlyjus, thank you for your reply. Here are my ubuntu machine details.


Could you please advise me further to troubleshoot the problem? Thank you.

Also, in the mean time, I tried sudo apt install libtbb and I get the following message on the terminal.


Could you please let me know how to troubleshoot this issue? Thank you.

hmmm maybe try the dev version?

sudo apt-get install -y libtbb-dev
