Error

Posted 11 years ago by zhengq
I used seepage face to simulate dewatering wells in a 3D model with 9 layers. I re-run this .fem file recently, but cannot get the same .dac file as I got before (very strange!!!). The pumping rate from the seepage face were reasonable from my previous .dac file. But the .dac file I got this time shows a unreasonably large value and variation in pumping rate. I am thinking to re-create the .fem file from the previous .dac file. But is it possible?

Thanks for help.

yes you can take the .dac to create a .fem file. make sure you use your timestep0

... and then just use  'Save as' and choose .fem as the format.

Does it allways work, or are there any situations, were one has to be carefull?
We were simulating a flow&transport model in an unconfined aquifer and I remember (rather sketchy), that we experienced some mass instationarity if we created a fem-file from a dac-file (we chose a timestep in the middle).
