X2t inlet fluids

[sam.bingham]

Hi,

I am trying to create a 2D reactive transport model that has an inlet fluid from the x direction, and a different fluid from the y. It appears that GWB only allows an inlet fluid in enter through the left and outlet at the right (i.e. along the x-plane). Is that correct or is it possible to have an inlet from the x and the y?

 

Thanks for any help,

Sam

Hi Sam,

When you let X2t calculate the groundwater flow field, the top and bottom boundaries are closed to flow. 

You can alternatively import the flow field from another program. In this case, you set up a table of the fluid discharge from node to node along x, and another for flow along y. X2t reads the tables and uses the values they contain to set the flow field. In this case, fluid may enter or leave the domain across any of the boundaries, not just the left and right sides, and you can specify unique fluids for each boundary.

For more information, please see sections 2.14 Groundwater flow, 4.3 Calculating the flow field, and 4.4 Importing the flow field in the GWB Reactive Transport Modeling Guide.

Hope this helps,

Thanks Brian, that makes a lot more sense!
