Seems that the log function is used outside the range on which it is defined (either 0 or negative). swak4Foam can't protect you from that. Of course you can always use max to make sure that you're...

This is swak4Foams obscure way or saying "I beg your pardon: how is the logarithm of a vector defined?". You multiply the vector u_f with a scalar and divide it by a scalar. Result is a scalar....

Sorry that this warning message is confusing. This really only happens during initialization. groovyBC can't do any calclations because some of the fields it uses in valueExpression might not yet be...

I don't think that this fields-entry does anything (that is only used in the simpleFunctionObjects AFAIK and groovyBC ignores it)

Is this some kind of test? To test my patience? Did it never occur to you that the problem might be that simply you and OF disagree on which column has which meaning? USUALLY in tables the value you...

No idea (and I'm not even sure which side you set the profile on. Also you only show the absolute value of the velocity. I've got no idea in which direction it goes)

But my first guess would be...

"read beyond EOF" usually is because the user made an error during editing (for instance forgotten ; ). In this concrete case the problem probably is that valueExpression is in the list of the...

I think it is rather clear if you look at your data file: the point 0.4758 is out of sequence (it is smaller than the point before it). Clean that up. You'll probably also have a problem in the end...

No you don't have to add anything to the controlDict.

I was just going through my own documentation "what does the fields-entry mean". Anyway. Lookups only work for scalars.

This is a boundary...

Yeah. You can either use timelines (for data that depends on time) or lookuptables (for a more general approach. This is what you'll want here). Have a look at the wobbler-case for a usage example.

What have you tried and what doesn't work? Be a bit more specific. The expression should look like this: "exp(3.31453803168746*log(5)-5.62522091753)" (more elegant if you use variables)

Something like...

Something like vel=min((u_f/K)*log(((pos().y+y0)/y0)+c),5)*normal(); should limit it (min(a,b) returns the minimum of a and b)

All available documentation is linked from the swak-page on the Wiki

Same problem in reverse: vel is a value defined on the points but valueExpression needs it on the faces. A well-set "toFace" should fix that

yp is defined on the vertices. Constants are defined on the face centers. Something like "toPoint(2.712)" would fix that. There are examples for that in .... the Examples
