Hi everyone,


I am learning how to make an optimization on an airfoil, with Hicks-Henne geometric variables. I want to add AOA to be a design variable. So the design variables including Hicks-Henne airfoil variables and AOA. The optimization problem is derived slightly from tutorial 7 "Optimal Shape Design of a Rotating Airfoil", which is a common example in aircraft design:
Minimize: drag coefficent at Ma = 0.75
subject to: CL=0.3, Max_THICKNESS > 0.12
design variables: Hicks-Henne parameters and AOA


I have added AOA to the end of "DEFINITION_DV" in .cfg file. The same mesh file was used as tutorial 7. When I carried out the process, something was wrong. Can someone help me? (I am using version 3.2.2) Thanks!

error displayed:

a non-zero exit code.. Per user-direction, the job has been aborted.

mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Hello to everyone, I am new in this forum.
I can't even run the tutorial because I always get the same error, like YoniHe. ("SU2 process returned error '1').
I tried for three weeks and I am still in trouble! Does anyone know which is the solution, please?
(The problem occurs only when trying to run a python script, the direct calculation works fine!)

Hello,
I am a novice user of CFD as well as SU2.

I installed the SU2v4.1.0-64 bit for Windows 7, Python 2.7.10-64 bit, scipy 0.16.1, and numpy 1.9.2.

I set the environment variables as each variable name of "SU2_RUN" and "SU2_HOME" with the same variable value "C:\SU2" which containing SU2_XXX.exe, SU2_XXX source code files and SU2_PY.

I could run the Quick Start tutorial successfully but still have a problem in the tutorial "Optimal Shape Design of a Transonic Airfoil" as the same problem like others.. (SU2 process returned error '1')

I followed the tutorial but the 'history_project.dat' as a result file was like the attached file with just one evaluation number..
And there was a message in the log_Ajoint file created in C:\SU2\DESIGNS\DSN_001\ADJOINT_DRAG directory after 'Exit Success' message.
------------------------- Exit Success (SU2_CFD) ------------------------

MATH_PROBLEM: improper option value for type math problem
OPT_BOUND_UPPER: invalid option name. Check current SU2 options in config_template.cfg.
OPT_BOUND_LOWER: invalid option name. Check current SU2 options in config_template.cfg.


Please help me to run and finish this tutorial.

Thank you!
