@disla. Is it possible to share your Mecway model file?
-
@Victor. Here are the arranged pics BTY, solver finished successfully after 2.5 hrs. Thanks to all involved with this thread especially prop_design
-
@Victor. I have submitted my full fan model with 453,000 nodes for modal analysis using Internal solver. It’s been more than two hours that solver is running on 16 GB ram. (I think it’s running see attached). Is this normal or something is wrong? T…
-
Thank you, Victor. Ran my blade sector successfully using Internal with TIE off. First mode was computed as 57Hz vs 61Hz using CCX. CCX is much faster than Internal. I will submit the full fan model shortly. Fingers crossed.
-
The full fan model has several bonded contacts between nylon blades and metal inserts. Internal can not used because of tie feature. Another reason is as @prop_design pointed out in earlier post a blade modal does not match full rotor frequencies. …

Hi prop_design, I added all system variables per your pic and ran a simple model for static solution with air loading and fixed constraint. Same results no solution. Is there anything that I’m missing.
-
prop_design, I added two variables to the system environment as highlighted in the attached picture. Still didn't get any results. No error message either. At this point, I am not worried about anything but to get the big model to run. Thanks
-
Prop_design, We are getting much closer now. I’m running a test case model with bonded contact using PARDISO solver. The solver runs and exits without any error but there is no solution. I think environment variables not being assigned is the pro…
-
Celebrated too early, I guess. Two test cases were static models. That’s why Internal ran successfully. My actual model has bonded contacts that are not allowed in Internal. Will continue on this tomorrow.

After placing .dlI files in the folder where ccx.dynamic.exe reside, I ran two test case using internal (not CCX) and it worked perfectly. Submitted the big ass fan with 873000 nodes…so far nothing has happened. Is this normal? Do you switch it to i…
-
I see your link. Let me try it
-
Where do I get such files
-
Anthony, I'm getting more confused now. I removed the ccx.dynamic.exe from the Mecway folder and put it in a different folder (Location.PNG) and ran the test case. The solver stopped immediately with an error message with no text/description as sh…
-
This is my current solver setting. Should I replace ccx.exe with the ccx.dynamic.exe one?
-
Anthony, I installed oneapi and put the CCX_dynamics.exe in the folder path as shown. Ran the attached test case and received an error. Any idea what theissue is now? thanks
-
Which workloads in Visual Studio should I sele ct?
-
prop_design, First of all, I highly appreciate your time and effort...you're a good mentor. Secondly, I started from scratch as you suggested. Downloaded VisualStudioSetup and Calculix_2.20.1_4win.zip. Then tried to install oneapi. Attached are …
-
prop_design, The first step following your recommendations was I downloaded the "Intel oneAPI Base Toolkit" from Intel website and tried to install it. The first snapshot shows the warning I received. I ignored the warning and got another message …
-
prop_design, Thank you for the info. I will follow your recommendations and most probably will have questions for you, if you don’t mind. Some of the words you mentioned are new to me. I’m not as expert as you are so we will see.
-
Hi Victor, I need to run a modal analysis of a non equally spaced axial fan to determine the frequencies and will have huge number of elements/nodes. On March 14, you replied to this thread and suggested that I download the CCX with PadtiX or Pard…
-
Thanks, Sergio.
-
Thanks, Victor. Merry Christmas and happy holidays!
-
Thank you, Victor. Appreciate the support.
-
Thanks. Much appreciated
-
Thank you sir. Ran it and results look good. One more question: Is there any option to display von-mises stresses form the pre-stressed solution?
-
I followed your procedure but did not get any where. Can you please setup the attached static run for a pre-stressed modal?
-
Thanks again
-
Prop design, Thanks for the effort. How would you approach this? Do you run static first or what? Could you explain the procedure step by step please. I have a static and modal analysis results of a stationary shroud. What should I do next? Thanks
-
Step files are attached. Thanks
-
Victor, In your previous reply to this thread, should't preload (-1000 N) be applied in the Z-direction instead of X? Thanks again - Hooshsim
