error
 
hi all i got one error,what can i do this

ERROR #002100048 has occurred in subroutine SU_BNEXT. | | Message: | | All vertices for a fluid domain lie on boundaries. This is | | considered to be a fatal error because control volume gradients | | cannot be calculated, leading to serious discretization error. | | | | A common cause for this error is a mesh which is only one | | element thick, without symmetry or 1:1 periodicity on the lateral | | boundaries. If you have this situation, and the domain is | | two-dimensional, please change the lateral boundary conditions | | to symmetry or 1:1 periodicity. Alternatively, for | | three-dimensional simulations, please ensure that your mesh | | has at least two elements across. | | | | Execution is terminating. This error message can be bypassed by | | setting the expert parameter 'boundary vertex check = f', but | | be aware that doing so may lead to sigificant solution error. | +--------------------------------------------------------------------+

Re: error
 
are you trying to model it as 2D or 3D ? If 2D then use extruded 2D option for mesh and define extruded periodic pairs.

3D model

Re: error
 
Hi,

In that case you have a meshing error. As the message says it appears all the nodes lie on the boundaries with no internal nodes.
