Queries regarding Altair Hyperworks CFD

I am running a simulation model for a single cell and a battery pack of 40 cells (I am attaching the photo with the query) . All I need to know is :

" In providing Heat source value, what does per unit volume means in single cell and in the battery pack?" For example: If I provide the value of Heat source as 30 per unit volume ,and assuming its a 18650 cell, so volume is 16 cubic centimetre, so heat value s (30*16/10^6) = 0.00048 W/cub m or something else and in case of battery pack of 40 cells what it will means?
What does CAD units signifies in Hyperworks, is it SI, CGS,MKS or something else?

I am highly thankful to you for providing me solution regarding hyperview queries.

AcuSolve itself is unitless, so you must ensure that all values used represent a consistent set of units - including units for the length/dimensions/size of the body itself. Most likely it is simplest to use dimensions in m, and everything else in MKS as well.

But if Acusolve is unitless, then if you go in preference and check the units , it describe CAD units. what does CAD units signifies?

Use the measure tool to measure the length of a known feature. Then you can determine which 'unit' is represented by the number/value returned from that measurement. In many cases we have material properties, boundary conditions, etc, in MKS units - so meters for lengths is simplest to use to be consistent.
