Hello all, whenever I try to solve this mathematical equation, it always gives me an error. 

I am pretty sure I am doing osmething wrong or not writing the equationj ina proper way, but until now havnt found out any solution to fix this problem. 

 

It will be very kind of your experts to kindly help me out in this small issue. 

The file is attached, in this file you will see "b_limit", which always shows an error for bing_bent, can anyone help me out to solve this please?

 

Best

b.ent^2 is an area I agree so is b.limit^2 right?

so both can be added isn't it?

Yes, this would be a possible unit consistent formula and the result would be a length, too.

 

The attached sheet in P5 format should help

b.ent is scalar, its unitless and you try to add a length (b.limit). This can't work as you can only add quantities of the same dimension.

Furthermore b.ent is just a range, not a vector as you might think.

 

What  exactly do you expect as result (and which unit do you think it should have?

Hello Werner,

 

It is really kind of you to help me out, I expect a range of b.img as a function of b.ent. 

b.limit being constant value calculated above. I would expect the units of b.ent in micrometers.

 

Further the results on second page with del omega i expect those reuslts as a function of b.ent and the units in reciprocal cms.

I would expect the units of b.ent in micrometers.

So b.ent^2 would be an area but b.limit is a length!

You can't add an area and a length!
