We are working on additional tutorials.

The E1 point is located in near field and is needed to compare pressure with direct calculation. If you are using the pimple or piso algorithm you need to set...

The library calculates the total pressure (p+p'). The static pressure is non zero because the FWH surface is located close to the body. If you want to determine [SPL](https://en.wikipedia.org/wiki/Sound_pressure#Sound_pressure_level) you...

Hi, we've switched to the OpenFOAM+ version of the OpenFOAM technology. The openfoam.org is no longer supported.

Hi, from the errorLog.txt it is seen that you have a very large continuity error just at the first iteration: > time step continuity errors : sum local = 0.000428673,...

Hello, it looks like there is a lot to be done with your custom solver. As the first step, can you post here LaTeX (PDF) or Doc file with derivation...

Hi, I think, you must add LTS support to your solver -- see https://github.com/unicfdlab/hybridCentralSolvers/blob/digitef-dev-1912/Sources/pimpleCentralFoam/pimpleCentralFoam.C and https://github.com/unicfdlab/hybridCentralSolvers/tree/digitef-dev-1912/Tutorials/compressible/LTS/ConvergingDivergingNozzle as examples. After that, you have to try running your code w/o shape adjustment....

Hi, this sounds very strange -- we tried that solver with very complicated cases (such as Vega rocket lift-off) and everything was OK. Can you attach here the whole case?...

Hi, I fixed several mistakes in your case. I. Serious mistakes 1. LTS was not designed to work with relaxation, so I commented all relaxation settins: > relaxationFactors { //...

Hi, Zhi! The FFTW3 library was not compiled or the environment path to it was incorrect. This library must be compiled with OpenFOAM and is located in the ThirdParty folder.
