nans in pops

[doc]

a couple of particles in my pop sim are reporting nan values for some of their velocities.

I was wondering if there's a way to identify these points and change their velocities to 0?

thanks

Hey Luca,

Not sure if you found a solution to this yet, but you could just group the particles usint strmatch() and then set that group Veloctiy to 0.

strmatch($VX, "inf")

thanks spencer, Silvina over at sesi support gave me a nice solution:

Since a comparison with a NAN is always false, you can try:

if( (testme -testme) != 0)
{
 printf("variable 'testme' is an inf.");
}

thanks for the help!

Jason, does the above look familiar to you?
