thanks Björn!!

However, I wanted to know if a part for the whole chain of VOC's (PCE; TCE, DCE  VC) that i can simulate,[b] how can I put other compounds (milk whey) that are not on the white papers V4- ch 1.9 explanations into the reaction kinetics?[/b], is there any one person that has ever come across to model a mutliple species or using a compound that has a lot of TOCs, to speed up de natual degradation?

or there is someone that has any idea how can i deal with the amounts of TOC (milk whey) that i am putting into the aquifer to make it understandable for feflow , the issue is that I have receive a model that was run on modflow GWvistas and the approaches for contaminants are already controlled by some specific packages (MT3D and RT3D),  and there is plenty of parameters like half life, Koc,  etc,  that i have no idea how to deal with them, even if I ask for help wihin the feflow porblem settings on the chemical species, I get i message that i have not the "wxhelp.exe", is that an special help for the transport?

thanks again for your collaboration and also to all the persons participating in this forum

Thanks for your reply

but there is something i wanted to know, there are some equations that according to the white papers are available somewhere  within FEFLOW i.e.  [b[b]]reaction_kinetics_PCE.fme[/b][/b] and so on for the whole chain of PCE degradation, but with the online installation i think those files are not available, can you please tell me where can i find them?

also do i have the right to receive the FEFLOW book when i buy a license?

Thanks again for your collaboration.

Hello guys!!

I am trying to simulate a reactive transport due to some PCE and TCE spilled in the aquifer studied (steady flow and transient transport), besides, I am using whey as injection product to speed-up the biodegradation processes.

I am having problems with the equations and the reactions that I need to fix to make these chemical reactions to occur, as similar to the actual observed data.

Can anyone give me some hint, information or a tutorial about how to set up a 3d transport model, and how to use other compounds within the reactive transport equations?

Hello everybody!

Does anybody has ever needed to cut a piece of a regional model  to create a detailed Model for an specific area?

is there any simple way to do this in feflow?

what happend with the groundwater table, the boundary conditions and the other parameters?

THANKS A LOT FOR YOUR HELP!!!

hello everybody

I am having an issue with a groundwater model that was given to me !!!, with 9 layers, thickness of 1st layer is 2 m (kx 8.6m/d), 2nd layer 10m (kx=0.0000864m/d), layer 3 15m (kx obtained by pest), and the other layers.... my interest regards the thrid layer.   
*  I have some layers with thickness ranging from 44 meters to 25m, and the size of the elements range from 2m to 25 towards the border of m model
*  with a BC to the north water table that is  +-267m and the lower BC (south) 256.44,
*  the area of entrance  is 1500m to the north and to the south is 3000m for each aquifer.
*  the model is covenging with an error of 15 centimeters OBSERVED VS CALIBRATED, but the problem is that i dont know why the RATE BUDGET IS GIVING MY VALUES COMPELTELY WORONG

I have an imbalance which is twice the entrance and i dont know to to fix this issue, discretization?

the model converges without problem, there is only one  log >>>>          PCG has a matrix with 159023th diagonal element <= 0.

I REALLY APPREACIATE YOUR EXPERIENCE TO HELP ME SOLVE THIS ISSUE!!! ( enclosed you have an image showing the 1st layer RESULTS WITH THE VALUES FOR THE RATE BUDGET)
