Hello, everyone. I am a beginners to FSI problems and now I have a problem about the icoFsiElasticNonLinULSolidFoam.

Every thing is Ok when I start the simulation by ./Allrun
However, the simulations abort quickly when I use the script AllrunPar. The log files is :

I am using the foam-extend4.1. Is there anybody knowing about this questions? Thank you very much.

[Aunura]

All right. Things go well when I switch to foam-extend4.0.
It seems that this is a bug in beta version.

Hi every one. I have come back.
Now I want to install the Fluid-structure_interaction toolkit.

I follow the guides of

https://openfoamwiki.net/index.php/E...re_interaction.

However, I my compiler encounter many errors like this :

One part of the make log is here:

Now my OF version is foam-extend 4.0. My ubuntu system is 18.04.3

Anyway, if someone know the reason of this problems, please give me a hand. Thank you .

May it be late, but for other person.
As it seen, the problem was from compiler.
Maybe changing from extend4.1 to 4.0 lead to defining gcc7.
As the Daniel mentioned, you should follow instructions as
solids4Foam twoElasticBeams tutorial: multiple FSI interfaces
So you need to clean first and run from first
