fix lb/viscous

Dear all

i want to use this command in my simulation : fix lb/viscous
but error happens: ERROR: Unknown fix style (…/modify.cpp:793)
also using fix lb/fluid resulted in above error.
please help me.


You probably forgot to install the USER-LB package. See the packages pages of the manual for how to install and compile packages.

Didn’t I answer this already?


Looks like you did.
