timeVaryingMappedFixedValue not working without headers!
 

Dear all foamers,


I am trying to surface sample the seabed pressure beneath regular progressive waves and imposing this pressure data to a new domain where a constitutive soil model is solving Biots equations for pore pressure development.

I use the surface sampling utility to map the seabed pressures in the wave model as such:

And that seems to be working fine. I copy my files to my soil folder into /constant/boundaryData/top/... When I try to run OpenFOAM complains that no header is given in the boundaryData files:

Now I am using OpenFOAM v1712 with waves2foam for the generating waves, while using OpenFOAM-1.6-ext for the soil model (as it was developed for this), but untill now I haven't had any problems with compatibility.

Anybody has any idea how to generate output files from surface sampling with appropriate headers, without having to do this manually or set up a script?

Best Regards :)
Peter

Quick answer: I haven't checked, but perhaps this is already fixed in foam-extend 4.0, so if perhaps the code you have in 1.6-ext were to build with foam-extend 4.0, it may solve this issue.


If not, then a possible workaround is that you rely on file inclusion instead:

1. Rename the file you have with the actual data, e.g.:
   
   Code:

   ---

   mv constant/boundaryData/top/0/p constant/boundaryData/top/0/p.data

   ---

2. Then create the file that will act as the wrapper, for example, place the following inside a new file "constant/boundaryData/top/0/p":
   
   Code:

3. The header is generic enough, and the last line will include the complete content of the original file that is now named "p.data". Therefore, you can copy-paste-adapt this file "p" for any other files, such as "p_rgh", but don't forget to first rename the data files first.

Hi, I met the following error, according to your suggestion.

Hi. Same problem here. Did you solve the problem?

Hi, I solved the problem but there is no way to simplify the procedure. You can only add the header one by one through Matlab or another programming.

Hi, I found there is a way to solve this problem by executing the following script directly. But what I need is p_rgh-constant. Can I simply add something here?
