Hey everyone,
I came across a strange behavior of the post processor in Mecway 4. Running "Pipe Clip" simulation I can't get results nor model displayed in the post-processor. Automatic scale results set up shows 0 MAX and 0 MIN. Changing MAX to any positive value displays it on the scale but model doesn't display. I have another Win 7 on the same machine and all works fine, I have used the same CalculiX installation bConverged 2.8 for both OS'es. I have reinstalled both Mecway and Calculix but the behavior still exist. Any suggestion?
best regards,
apadzak

I'm couldn't answer your question but the results displayed okay on Mecway version 4.0 with bConverged ccx2.8p2 solver on a Windows 10 Pro 64-bit. See video below. The file used in the video is attached.
There is a problem that causes results not to be read correctly which comes from a missing environment variable that CCX requires - PRINTF_EXPONENT_DIGITS=2 and that will appear as a corrupt .frd file.
Also, could you have a look at the table in the solution. Does it show any data? Are node coordinates all zero or something else like NaN? That will determine if it's a graphics problem or the data Mecway has is corrupt.
I have written out an input file from Mecway for Calculix and I've solved using Jeff's bConverged Launcher (bConverged_2_8_win_003_X).
I've imported the results file into Mecway and see the mesh but I don't get a stress contour displayed; the contour min/max values are evident.
I am expecting that I've missed a step in how to display the results.

Is a little confuse this behavieur, in other postprocessors the initial increments is always adjusted to blue color (zero stress/strain...)

The time slider was the vital step. I'm really impressed with Mecway, it is a real treat to write out an input deck and it runs in Calculix. I only just realised that I could read the results back into Mecway; I'm more inclined now to also try and run ccx from within Mecway. I read an enhancement request with regard to ccx runtime messages and tailing the .sta file, are these implemented now?
Regards, Tim
Would be nice to have this two windows (ccx output and .sta records) integrated in Mecway.

Thanks for your message. Sorry for late reply, I was away, now I should be quicker with answers. I couldn't find .frd file, whole folder is attached. Result tree don't display the table. There is something what I ignored before but in the solution folder "Components" there is 359 elements which don's have material assigned to it - pls see attachment. In the "Components & Materials" branch in the outline tree all looks ok with regards to materials assignment and displaying highlighted components.

Also, could you have another go at the table when the problem is happening? Use the button near the right-hand end of the lower toolbar.
The error message on the component is spurious and you can ignore it. It won't be there in v5.
Victor, I have tried another file which can be analyzed with MW and CCX, I have chosen CadAssembly. CCX wasn't able to solve as in the Pipe Clip example. I have selected exporting solution to CSV and only MW is able to do it, CCX didn't generate anything so I have used clipboard to past the solution manually. I did the same with both CCX solved solutions. Pipe Clip solution looks like it doesn't change time step, even when I tried to change it manually for 0 to 20 time steps. I think it may be some system variable missing, which is required by CCX. Please have a look at attachments.
Thanks,
apadzak
P.S. Sorry for the size of the file...
Could you please try opening the .frd file in the MecwayInstance64574871\Ccx folder you attached in a previous message? That seems to be a correct file and I can open it OK, so it looks like CCX is working correctly, but apparently your Mecway is ignoring all the data values when it reads it, and only reads the names of the field variables and the node numbers. This check should determine if the problem is reading .frd files in general, or only when it opens them automatically after solving.
After this, I'd like to ask you to use a special debugging version of Mecway to help narrow it down further if you don't mind.
I did try to open .frd file and it opened in the system where Mecway works fine (there was some error message that CGX can only display displacement) but I couldn't animate results though. I think in the other system I tried to open the .frd file and it was opening without model display. I will confirm that anyway. I don't mind testing Mecway with some enhancments, it will be a pleasure actually.
Thanks,
apadzak
I did have a look at the .fdr file in the system with problems and it displayed in the same way as in the system where all results worked fine. Please have a look at the screen videos I made and test suite summery. Videos are here: https://www.dropbox.com/sh/5jyi4t5ixd737eb/AAClwV1KUfHOswGfJM0kAMlMa?dl=0
Are results of CCX Test Suite of any help?
I did it and there wasn't any error displayed but maybe I missed something.
If you have any suggestions please let me know.
Thanks,
apadzak
No need to check CCX. It's apparently generating a valid .frd file because you found that CGX can open it OK, and I can open it with Mecway myself too.
Opening .frd file Via Mecway was successful. Good news. Is that mean Mecway can't find the right file to lad it after analysis automatically? If you need some more details please let me know.
Thanks,
apadzak
Next I'll create a modified program to help debug this. That'll take a few more days. Thanks for all your effort in helping with this.
The same with thermal analysis. Works ok on experimental system, doesn't work on other system apart going to temp folder and opening CCX result file. By the way, is there any chance that I can change where the solution is being saved. System partition isn't best for me due to the size constraints so I would prefer to have some flexibility in that case.
I am happy to help with testing the bug...
Thanks,
Arek
P.S. Can it be some confusion related to two Win OS on the PC?
