Dear ogs users,

I am setting up a mulicomponent MASS_TRANSPORT model with transient BC for different components. I define my transient BC (time concentration data) as a function in the FCT file as follows:

#FUNCTION

$TYPE

fct_BC_POINT0

$VARIABLES

TIME Tracer

$DATA

0 0

3600 1

7200 0

10800 0

works well for one component. Can you define such time concentratoin function for several components at once and asses them in the BC file through $PRIMARY_VALUE ? I tried but this did not work:

#FUNCTION

$TYPE

fct_BC_POINT0

$VARIABLES

TIME Tracer Tracer2

$DATA

0 0 0

3600 1 1

7200 0 1

10800 0 0

I know you could define a seperate functoin or each component such as:

#FUNCTION

$TYPE

fct_BC_POINT0_Tracer

$VARIABLES

TIME Trace

$DATA

0 0

3600 1

7200 0

10800 0

#FUNCTION

$TYPE

fct_BC_POINT0_Tracer2

$VARIABLES

TIME Trace

$DATA

0 0

3600 1

7200 1

10800 0

But it would be easier to have one data table with several component concentrions in.

Any solution?

Best,

Johannes
