Fortran 157 error Access Violation

Recommended Posts

Hi,

I tried to use

Read Grid Zpts == ...\<file>.asc

to assign elevation to my FV mesh. It is a large ASCII grid (~100GB) which is in the same projection as the mesh. The RAM on the system is much higher than the file size (~192GB). I have read/write access to the folder where the ASCII grid resides. The file unit is being opened; memory being allocated and the file unit is being closed, but it crashes with the fortran (157) access violation error as soon as it is closed and the model doesn't proceed any further.

Can anyone help me with this?

Thanks,

Kaushal

Thanks to Mitch Smith's suggestion, I converted .asc to .flt and the file size dropped from 100GB to 18GB. Read Grid Zpts worked fine with the smaller .flt
