Hello!

I want to set a user defined function as a boundary condition. For example,

ebc_1 = { 'ebc_inlet' : ('inlet', {'u.[0,2]' : 0, 'u.1' : myfunc}, }

myfunc(ts, coors, **kwargs): ...

what type of an object is coors? how can I write the x, y and z coordinates in terms of the variable coors?

Check the examples in [1]. It is an array of the coordinates, the components can be obtained simply as:

x, y, z = coors[:, 0], coors[:, 1], coors[:, 2]
