Hello everybody!

I have got a problem with scheme commands and unfortunatelly I haven't found any solution here.

I need to set a few scheme variables for my UDF.
I have already solved my problems with UDF and defining a variables with couple commands:
(rp-var-define 'NAME1 0.0 'real #f)
(rp-var-define 'NAME2 0.0 'real #f)

When I type them in TUI everything is OK, but when I put those lines in my journal (with another "common" commands) I've got an error:

Error: A journal or macro has already been started.
Error Object: #f

It appers while fluent executes first journal command after defining all scheme variables using: (rp-var...).

Anyone knows a solution?

Best regards,
Michal.s

what is your next line?

My next line:

/define/boundary-conditions/wall wall-sphere 0 no 0 no yes temperature no 20 no no no no 0.0025 no 0.5 no 1

Hi Michal.s

I do not think that these lines are the (only) cause of that error message.
(And I think this is where AlexanderZ's question was leading as well.)

You cannot read a journal while you are writing a journal. You cannot necessarily run a read-journal command inside a journal -- this may have changed in recent versions, but it certainly used to be forbidden.

By the way, it is generally discouraged to rp-var-define the same RP-variable twice. I'm not sure how serious the consequences are. The UDF manual used to contain a nice little Scheme function to guard against this -- see for example https://www.sharcnet.ca/Software/Flu...df/node107.htm. I'm not sure why this disappeared from the documentation.

Good luck,
Ed

if previous comment doesn't help, may may try to use other approach.
Change format of your file from journal(mixed with scheme) to scheme.
And run scheme file not journal.

to make new format you should change the way, how your execute TUI commands

Was

/define/boundary-conditions/wall wall-sphere 0 no 0 no yes temperature no 20 no no no no 0.0025 no 0.5 no 1

New

(ti-menu-load-string (format #f "define boundary-conditions wall wall-sphere 0 no 0 no yes temperature no 20 no no no no 0.0025 no 0.5 no 1 \n" ))

It means, you can access all TUI functions using ti-menu-load-string scheme command.

Hello Again,

I tried to simply rewrite my journal.
I don't know what could be the the problem, but currently everything is OK.
Hope that nothing will crash.

Thank you for all suggestions. I will try them if the problem will appear again.

Best regards,
Michal
