Error: "System error: Not found: BAF_1.C_1_2_3"

Hello,

I have built a biofilter model with 5 layers of biofilm. I have tested my model with ASM1 <<instance>>, the model can run without error. After that, i changed instance with some new components added. All the grammatical errors have been solved.

When i ran simulation, i found a system error: Not found: BAF_1.C_1_2_3. I know that the ''BAF_1'' is the bloc i built. But i don't understand what dose ''C_1_2_3'' means. C may be the concentration.

Can you help me to figure out what dose that means?

Thank you very much!

Best regards.

Hi,
yes: "C_1_2_3" is the expansion of the C vector (or matrix), where 1, 2, 3 denote specific indices.
I assume you have a vector C[i, j, k] right ?
[list]
[li]'i' may indicate the component index (in the state vector), e.g. (ref ASM1) H2O is 1, S_I is 2, etc.[/li]
[li]'j' may be the layer index, 1-5[/li]
[li]not sure what 'k' means in your case ...[/li]
[/list]
If you can provide more details about your model, I may be able to help you further.
