Re: LTRANS and wetting and drying

Yes, that would do it. I believe the code will only reflect a particle 3 times before it gives up and calls it out of bounds. If you would like to ignore these particles, you can change the error flag towards the bottom of LTRANS.data to 3. It will set those particles out of bounds, but continue to ...

Re: LTRANS and wetting and drying

What is the error code you are receiving? LTRANS should not work with wetting/drying, as it loads the boundary information from the gridfile, and is static after that. You may still be able to successfully run your simulation, if the particles do not interact with that area of the domain, or if the ...

Thanks,

Yes, actually it can!

We have not released this code to the public yet, but I believe some others have independently done so. Keep on the look out for LTRANS 3.0!

Re: LTRANS "jumped over a u element"

Is there a recommended idt value, maybe depending on the spatial resolution? Yes, the value is highly dependent on the spatial resolution and the particle velocities. The model will not allow a particle to move through a gridcell without being effected by its properties, so smaller gridcells and la...

Re: LTRANS: Larval TRANSport Lagrangian model

Hello All, As Chris Sherwood mentioned, we have been working on polishing LTRANS, and fixed some compiler specific issues. Please checkout the LTRANS webpage for the code, and information on the updates. Please report any issues you encounter. Should they be compiler specific, in the meantime I can ...
