These constraints include 2 interior partitions. By default, the two interior vertices along each of these edges has the freedom to be moved. By including them in the interior of a res command, they no longer have that freedom, but are interpolated as any other interior node along the edge. Inserting Partitions for the Inlet A hole is needed in the mesh for the inlet pipe. No Equal Spacing on the boundaries partitions were formed in the block command to anticipate this hole. Partitions will be added using the insprt command. This method of forming partitions in the part has two advantages. First, you do not have to plan for the location of the required partitions. It is possible that you will discover that some existing partitions can be used for the unplanned feature, reducing the complexity of the part. In fact, you will use the existing 3rd i-partition for the inlet pipe hole. Secondly, when a partition is inserted, it is automatically placed along an existing mesh line so that you not have to determine the initial coordinates for the partition as you would if the partition were specified in the block command. The inlet pipe part will have a flange that connects to this part, so the hole in this part must be made larger than the inlet pipe. The cylinder used for this hole is similar to surface 8, but with a larger radius of .5. sd 9 cy 2.5 -1 1.75 [cos(-80)*cos(-25)] [sin(-80)] [cos(-80)*sin(-25)] .5 Three partitions must be inserted. The insprt command has 4 arguments. The first number is almost always 1 indicating a standard partition. When a partition is inserted, it is always relative to an existing reference partition. The new partition will be either before or after this reference partition. The second argument can be one of the following values: Existing Partitions 1 - before the reference i-partition 2 - after the reference i-partition 3 - before the reference j-partition 4 - after the reference j-partition 5 - before the reference k-partition 6 - after the reference k-partition This number is followed by the reference partition number and the number of elements away from that reference partition.
