The phrase "are needed to simulate" is correct and usable in written English.
It can be used when discussing requirements or components necessary for creating a simulation or replicating a scenario.
Example: "Several parameters are needed to simulate the effects of climate change accurately."
Alternatives: "are required to replicate" or "are essential for modeling".
GENS does not consider LD between DPL and surrounding genetic markers, so more sophisticated simulation methods are needed to simulate linked markers using genetically related individuals.
Alternative methods, such as continuum models, are needed to simulate such systems.
Consequently, equivalent modeling techniques are needed to simulate the pattern-specific distortions induced during pattern transfer.
A large number of grid cells are needed to simulate very large field reservoirs such as those in the Middle East.
This paper revises the simulation and optimization techniques, as well as the tools existing that are needed to simulate and design stand-alone hybrid systems for the generation of electricity.
Complementary advanced numerical models are needed to simulate the flexural behavior of CFST to extend the experimental research and develop predictive tools required for design and evaluation of structural systems.
Hence a model is needed to simulate this phenomenon, precisely.
Once the orbit and the attitude of a spacecraft are defined, it is needed to simulate the performances of an in situ instrument.
It is appropriate for cases where the implementation of boundary conditions can be difficult when applying other methods and in cases where parallelization of the computations is needed to simulate large systems.
By changing the velocity field and diffusivities, only one distribution function was needed to simulate the melting with natural convection in PCMs and conduction in fins and enclosure surfaces.
As it is indicated in Table 3, the proposed method outperforms the high performance algorithms such as SAI and optimized spline in terms of the average time that is needed to simulate the algorithm, and features a higher implementation speed.
