I am trying to run a simulation (transient flow) on a HPC-System. Fluent is supposed to read a case and data then run a calculation, for which I define time step, number of time steps & number of iter\/time-step. The input Journal looks like:<\/p>\n

————————————-<\/p>\n

rc SYS-3.1-1-00923.cas.gz<\/p>\n

rd SYS-3.1-1-00923.dat.gz<\/p>\n

solve\/time-step 0.01<\/p>\n

solve\/dual-time-iterate 1000 100<\/p>\n

wc Ergebnis.cas.gz<\/p>\n

wd Ergebnis.dat.gz<\/p>\n

exit<\/p>\n

yes<\/p>\n

————————————–<\/p>\n

In the output file the only problem is with the 2 command lines:<\/p>\n

solve\/time-step 0.01<\/p>\n

solve\/dual-time-iterate 1000 100<\/p>\n

since I get for both the error:<\/p>\n

Error: = (equal): invalid argument [1]: wrong type [not a number]<\/p>\n

Error Object: #f<\/p>\n

Reading & writing case & data files are totally fine! There is no problem.<\/p>\n

I searched in Internet & in many documentations are the two command lines used. So here is my question are the command lines to run transient simulation correct? <\/p>\n

<\/p>\n<\/p>\n

Thanks for the help!<\/p>\n
