added a zero pressure gradient tripped turbulent boundary layer example

[Mr-2c]

the mesh is a bit large, so let me know if it is appropriate as an example. also the trip.f90 is basically from @vbaconnet from a code from @MartinKarp based on the original code from @adampep, so not sure how the acknowledgment works here, but I added all their names to the trip.f90 file

@Mr-2c just two initial things:

• Remove the .log
• Remove the mesh and instead add the genmeshbox command to genereate it to the readme. If you are using a file to prescribe the element size distribution, add those.

Unless the mesh is huge, can't we store both the compressed nmsh and the genmeshbox command?

I somehow wanted to have the .log so the users can see how the mesh was created. but I can remove it if it is inconstant with our guidelines

[timfelle]

You can easily just add that to the readme as well. Something like:

To generate the mesh use some command
The expected output should be

xmin, xmax, Nel, periodic:    0.000000   162.500000   96 F
ymin, ymax, Nel, periodic:    0.000000    65.000000   64 F
zmin, zmax, Nel, periodic:    0.000000    78.000000  112 T

great idea, will do

I am adding the genmeshbox command to the readme file. is that sufficient?

[Mr-2c]

the full mesh is 1.8GB before compression and 253MB after compression, so I think it cannot be included. the current smaller one just let me know whether you want to keep to remove, I am fine either way...

[timfelle]

I think it would be best to just remove the mesh and let the user generate it themselves. Especially if you need to compress the mesh to include it.

[timofeymukha]

We cannot use the built-in Blasius?

[njansson]

As long as the mesh is axis aligned, built-in "should work"

[Mr-2c]

I will add a comment to emphasize this but will somehow want to make as few changes as possible now, unless you think it is important

[timfelle]

Could we clean this up for the final state of the PR.
