error by using root (growth) density model

[hussein delfin]

Hi dear Dr,
when i tried to use growth model to distribute root density in 2D version i always get this error
../rootdens_growth.C:176: assertion '0.223123 != 0.185623' failed in set_density (error)

1. what should i do to fix the error??

2. can i set specific root dry matter (Wroot) when using GP2D (root density model)???

3. i have irrigation experiment of the same crop but with 3 different soil texture, can i use different values of (DensRtTip, SpRtLength) in each soil texure when using GP2D model???

best regards
hussein

1. I don't believe that model is ready to use, sory.

2. Not sure what that means. WRoot is calculated dynamically by the crop model.

3. You can make three different variants of the same crop with different parameters.

Regards,

Per A.
