Mapping surface results in Acusolve

kpk

Hi everyone,

How can we map results in AcuSolve, for example as shown in image problem1 is solved in AcuSolve and results are known, i want to map surface S1 results (pressure, film coefficient etc) to problem2 surfaces (S2,S3,S4,S5) and solve in Acusolve

If a process can be determined, this would only apply to base variables - pressure, velocity, temperature, etc. Can you describe more of what you would like to do with these mapped results? Are they to be Nodal Boundary Conditions (constant through simulation), or Initial Conditions (change as simulation proceeds)?

Why not solve the entire 'Problem2' as one simulation, without the mapping process?

Because problem1 has elements approx 5cr (more than 2 days to solve) and for problem 2 (4x5cr elements) difficult for system to handle, so i am planning to use s1 surface heat transfer coefficient (Nodal Boundary Conditions (constant through simulation))and map it to surfaces (S2,S3,S4,S5) and solve it as conduction problem in AcuSolve

SimLab has a mapping capability you may be able to use, which ultimately creates nodal initial condition files. (You point to those files to use for nodal boundary condition files instead...)

1. Use acuTrans to create the data files from Problem1 (S1) in X/Y/Z/data for each quantity of interest.
2. Create copies of that file for eventual use as S2/S3/S4/S5
3. In each of those copies, modify the coordinates to the location appropriate to S2/S3/S4/S5
4. Once each file is modified to the appropriate x/y/z location, combine those files into one large file.
5. Load the desired mesh for the combined Problem2 into SimLab and go through the process to create the NICs from those prepared x/y/z/data files. (Create a "Flow Solution" that with the mesh and setup you want to solve for Problem2. In the Analysis ribbon you'll click on Initial Condition.)

NOTES:
You would ultimately have separate files for each desired data field - one for velocity (3 components), one for pressure, one for temperature, etc.
You may need to remove any duplicate x/y/z locations from the large combined files.
Once you write the input file and mesh for Problem2 with the mapping completed, you'll need to modify the .inp to create NODAL_BOUNDARY_CONDITION commands pointing to the various files referenced by the NODAL_INITIAL_CONDITION commands. (Or - if you simply turn off the solve of some of those equations, you can leave them as NICs.)
Try this with a small model first to understand the process and see if it works.

Thank you for reply, i will work on it.
