The subscription of Control Valve Performer – simulationHub app is based on a simulation credits system. After you purchase Control Valve Performer – simulationHub app from the Autodesk app store, you can purchase a subscription plan for the app. As Control Valve Performer – simulationHub app performs CFD simulation to provide the user with performance curves of control valves, computational resources are engaged on servers to run the simulations. The subscription plan covers the cost involved in utilizing these computational resources. There are two subscription plans: monthly subscription plan which is for USD 500 or yearly subscription plan which is for USD 5500. Following are the details of two plans:
1. Monthly subscription plan USD 500 (meant for light use): In this subscription plan you will receive a month’s subscription which consists of a basket of 100 simulation credits. Each simulation credit is consumed when one angle simulation is performed. One simulation is required for each angle. A performance curve consists of simulations for multiple angles. Your subscription will end after the duration of one month or after performing total of 100 simulations whichever comes earlier.
2. Yearly subscription plan USD 5500 (meant for heavy use): In this subscription plan you will receive a yearly subscription which consists of a basket of 1200 simulation credits. Each simulation credit is consumed when one angle simulation is performed. One simulation is required for each angle. A performance curve consists of simulations for multiple angles. Your subscription will end after the duration of one year or after performing total of 1200 simulations whichever comes earlier.
The above subscription plans are based on our average usage estimates of 100 simulations per month. Based on your requirement and estimated usage you can carefully review above two plans and decide which one suits you the best.

All control valves have an inherent flow characteristic that defines the relationship between valve opening and flow rate under constant pressure conditions. Each process operations needs valves with specific valve characteristics including fast opening, linear or equal percentage.
The valve needs to be designed based on the process control requirement. Predicting the valve characteristic during the design phase is critical to meet the end control requirement. The valve characteristic depends on the way the flow passage between moving and stationary components is managed. The design of moving components like the disc, plug, ball etc. and its relative position to stationary components decides the overall characteristic of a valve. The designer needs to know the effect of the change of many valve geometrical parameters on its flow characteristics.
Understanding flow characteristic in a control valve is a complex process. Fluid flow entering the control valve undergoes various flow behaviors before it leaves the valve. Analytical calculations are impossible in such cases as the flow undergoes separation, change in direction and wall resistance. Computational Fluid Dynamics is an accurate method to predict the exact flow behavior in the control valve.
Control Valve Performer app by simulationHub is built for designers. This app is built taking into consideration that valve designers does not have any knowledge about complex CFD processes. The app asks only the inputs and details which the designer can give easily. It does not ask any inputs related to CFD including flow conditions, meshing and solver details etc. All the CFD processes are automated with customized solution settings for control valve flow simulations. The results are presented in simple and ready to use characteristic curve plots.
Control Valve Performer app by simulationHub needs only the following inputs from the designer:
- Create / import control valve geometry
- Select moving components
- Provide axis of rotation / lift
- Provide opening conditions
And this is all needed to get a characteristic curve of control valve using this app. The app then takes all the inputs and does a number of CFD simulations to predict the characteristic value at each opening. The computations are done using simulationHub’s cloud computing resources and do not use any local computer.
