model is fresh without any analysis. still it is giving warning. After importing single results file in postprocessor two files get imported. with same name. please suggest solution. please also comment on first warning
There won't be a "file" named last_run_2. This happens when you change the model through an acf-command during the simulation. Adams then splits the results in two (even though it is technically one file and one run.
To avoid this, add
output/noseparator
to your model or acf file. That forces Adams to treat it as one continuous analysis.
