Hello Mehdi,

If the results from single precision are different than with double precision, then it means you need to run double precision. I always run double precision. Here is more information from our knowledge database:

”I almost always use double precision. The only way to know with any degree of certainty whether single precision is adequate or not is to compare the single precision solution to the double precision solution. If there is good agreement, then single precision may be deemed adequate for that particular model (and likely so for other models that are similar).”

Let me know how it goes.
