Input and Result Quantities in Quantity-Sized Calculations
To calculate quantity-based in DIAdem, click the Calculate Quantity-Based button on the DIAdem ANALYSIS toolbar. When executing quantity-based calculations, DIAdem checks whether the selected physical quantities can be used in the same calculation. If DIAdem cannot execute the calculation due to inappropriate physical quantities, DIAdem displays an error message. Refer to the Help page Calculating Quantity-Based and Non-Quantity-Based in DIAdem for the conditions and rules for quantity-based calculations.
Additional rules apply for the Calculator and the Calculate command. Refer to the Help page of the Calculate command for further information.
Some functions need dimensionless input quantities or return dimensionless result quantities. These physical quantities all have the exponent 0 for all base units. 1, %, and dB are examples of dimensionless physical sizes. If you do not specify a result quantity, DIAdem uses the unit 1 as the result unit for these functions.
For most VBS functions the physical input quantity is arbitrary and the physical result quantity dimensionless. The following functions however need a special physical input quantity or return special physical result quantities:
