ModelBuilder how to refresh fields from layer

[JoseSanchez]

Hello everyone,

how can I refresh the fields from a feature class in a model after this feature class has its structure changed.

I am running an Append, and the new fields added to the FC are not there.

Thanks

Have you tried using refresh catalog,
