[IDV #JKM-362576]: Java heap space



Youssef,

You have a few different options here:

Choose a smaller number of time steps for the WRF output you are trying to load
into the IDV.

Increase the amount of memory available to the IDV:
https://www.unidata.ucar.edu/software/idv/docs/userguide/misc/PerformanceTuning.html

Find a computer with greater memory capacity and use the IDV from that computer.

Best,

Unidata IDV Support
