There is no output to .vtu generated in the fsi-results folder

[LeoXXVII]

Currently using Gridap v0.16.5, GridapGmsh v0.4.2, and GridapFSI v0.1.0

The terminal gives a result, but there is no output created in the corresponding folder.
The only file is "fields.pvd" that has nothing inside

Hi @LeoXXVII , which driver are you running? Are you adding the argument is_vtk=true when calling main?

By the way, the branch refactoring_to_Gridap_0_17 is already working with [email protected] and GridapODEs#TransientMultiFieldCellField. I will merge it to master once GridapODEs is updated.

[LeoXXVII]

Sorry for not replying before, I am using the ElasticFlag_FSI1.jl drive.
Also, no I didn't add the is_vtk. I tried, and yes, it gives differents .vtu results for each step (sadly in the name of that file it's called fields_x.0.vtu and the ".0" part interfere to visualize on paraview as a group, so yeah, i just change the file name)

Also, I was in the middle of writing the result it wasn't in the description, but right now it works it.
But I still didn't update to Gridap 0.17, because of the DiscreteModel() thing. I write about that in this thread gridap/Tutorials#125 (comment)

another example about the names of the files.
It can't visualize in only one model on Paraview.

Hi @LeoXXVII , you should be able to open the file "fields" in paraview and this should contain all time steps of the simulation

[LeoXXVII]

I mean, with that "dot", paraview separates the files into 9 groups.
I recently edit all the files names to delete that dot and work well.

but if you refer to the field.pvd..... em...that contain nothing.

Aside, em... The second test in the readme.md of GridapFSI.jl

The output is different compare with the first example, I mean, is the same model but different time-lapses, and no parameters like Re, rho_s & Um. Causing this result. (I change the final time for 1 second instead of 10 sec, tf=1.0 for less space usage)

This is an image of 0.04s passed

Aside, which program do you use for the FSI2.gif? I mean, if this didn't get by the output in paraview.

[oriolcg]

This is the result that I get at t=0.04 with the latest version merged to master.

calling with this set of parameters

output = main(
         strategy="biharmonic",
         alpha_m=1.0e-6,
         alpha_m_weight="volume",
         model="../models/elasticFlag.json",
         dt=0.01,
         tf=5.0,
         theta=0.6, is_vtk=true, coupling="weak"
         )

Note that this is with a coarser mesh and I use the weak coupling approach.

Regarding the .gif file, I just use a web application to convert a set of png files to a gif.
