trouble with saving file using adaptive time step

matos · April 30, 2018, 11:40

I'm trying to save ascii files at each time step, but when I use adaptive time step, fluent sometimes repeats the same time step and I get a message for overwriting my file because the name is the same. What I need is to tell fluent to overwrite (or just write the last guess of dt for each time step) the file without the need of clicking as you can see in the attached figures.
Someone had this problem before?
Thanks for the help

I don't get why Fluent would repeat a timestep...

Nonetheless, you can disable the prompt by going to file => batch options and uncheck confirm file overwrite. Then it will always overwrite. Note that you need to remember to set this batch option every time you open the case (it's a safety feature).
