A comma separated value format displacement file has the .csv extension and follows this format:
-
The first line has only the conversion factor value, which is used to divide the translational displacements (DX, DY, and DZ) to convert them to the internal unit of inches.
-
The second line is either Y axis up or Z axis up to indicate the CAESAR II Coordinate System that the following displacement data corresponds to.
-
All the remaining lines are displacement data lines:
-
Each line could have 58 values: Nodes X, Y, Z and the 54 displacements for the node (6 degrees-of-freedom times 9 vectors is 54).
-
The first value is a node number, which is required.
-
The following three values, the three coordinates of the node, are ignored.
-
The final 54 values are displacements of the node, in the order: DX1, DY1, DZ1, RX1, RY1, RZ1... DX9, DY9, DZ9, RX9, RY9, RZ9. They are optional. You can specify all 54 values, or not a single value, or any number of values in between.
-
Values are separated by commas. The length of a displacement data line is not fixed.
-
Because each value is followed by a comma, a comma counter is used to determine the placement of the value in a CAESAR II model. For example, values at positions 5, 8, 55 and 58 correspond to DX1, and RX1, DZ9, and RZ9 of the node in the model, respectively.
-
A value can be any number of characters in length. When there is no displacement value, you can use a zero length or blank field. For example, if a comma is followed by a comma, or if a comma is followed by blank spaces and then a comma, it means that its corresponding location in a CAESAR II model has no displacement value.
-
Generally, the csv format is recommended for a displacement file because it is relatively easy to generate and maintain in Microsoft Excel™. The fixed format of a displacement file is more difficult to maintain.
A displacement file from version 5.10 or 5.20 cannot be used directly in CAESAR II Version 12 because the formats are different.
