Hello,
I got my simulation reults, but problem is that I can not read them:
dimensions [0 2 -2 0 0 0 0];

internalField nonuniform List<scalar>
5963410
(–Çïµ·?†0E†½?íÃí5˜vµ?É¡8Ú+¼?5âb|¾?í@ÔI{Ù¹?C ,Õâ¾?Œ†Vm±?xðšl¯º?&ö!o°»?½§)>{´?0Ó]£³?n«’K/°¼?v,dâ½?Šõ…!5v¸?Fµ*]XC¾?0ßþÂ¿?îLG'”O´?þ;’¹?ò%¼¡PD³?…º€¢¦â²?ÜÃÊ2œ »?&Ö4´<óµ?…ö2›–k´?è¢ô#Œ¨?'l›ó¤«?f}VÛÓÖ¢?Ò(‚æ‡ ½?!ƒß«½?ºfÕžø¿?QÂÙK×µ?ÎoÝD

Has anyone same problem? How can I solve this problem.
Thanks for your time!

Quick tip/idea:
- Open system/controlDict and ensure you have following selection

Code:

writeFormat     ascii;

writeCompression uncompressed;

Hello guin,
Thank you for your tip. write format is binary and write compression is off. I changed them as you told. should I run simulation again? because after change I didnt see any difference in results.
Thanks!

But, please, be careful!

If your mesh has actually 5963410 elements (as it seems from your post) disabling compression may increase a lot the disk demand for your results. Ensure that you have enough free space in your disk before restarting the simulation. Alternatively, you can just write out results using a longer interval or take advantage of purgeWrite keyword (more info at https://cfd.direct/openfoam/user-guide/v6-controldict/)

Yes. If your simulation takes too long and you are only interested in the last results, you can resume it from the last time and let it run for a single additional timestep e.g. (again in system/controlDict):

Code:

startFrom       latestTime;

stopAt            writeNow;

Thank you so much!!
It perfectly works.
