Using log function for velocity

Using SimScale Fluid Flow / CFD

Hello,

When I define inlet velocities, I can use several functions like sin, cos, log etc. So here is this log referring to Log-to-base-10 or to-base-e?

I would assume that it is natural logarithm but log-to-base-10 is more commonly used. So I am a bit confused as to what base this is referred to?

Thanks

@ajaybharish - thanks for pointing this out, it is not so clear :confounded:

I believe it is log to base 10 but will need my colleague @gholami to confirm.

Best,
Anna

@ajaybharish, it’s natural logarithm (base e)
