The phrase "a multitude of numerical" is not correct as it is incomplete and lacks a noun to follow "numerical." You can use it when referring to a large number of numerical values or data points, but it needs to be part of a complete thought.
Example: "The study presented a multitude of numerical data that supported the hypothesis."
Alternatives: "a variety of numerical" or "a range of numerical".
Thus, to investigate numerical representation we utilized tasks that engage numerical, rather than mathematical, skills, as mathematical measures may be affected by a multitude of these non-numerical factors.
The target audience of this paper are the numerical modelers from a multitude of disciplines who are interested in enhancing the performance of their serial codes.
It has shown to provide useful results in many complex situations, where the physics of the system involves many degrees of freedom and a multitude of different length scales, generally rendering its numerical treatment on a detailed level computationally intractable.
Technical flow devices are usually optimized by using numerical algorithms that analyze a multitude of design variants for the flow restraining geometry until an optimum solution is found.
This paper presents a sensitivity analysis on a numerical tidal stream turbine model where a multitude of input parameters' effect on the load output were determined.
To enhance the understanding of wind fields associated with these storms a three-dimensional numerical model was developed to simulate a multitude of idealised downburst scenarios and to investigate their near-ground wind characteristics.
Given the complexity of the system, with non-symmetric helium headers and collectors, a multitude of parallel helium channels and spatially varying heat sources, a refined numerical model was applied to understand in detail the BU's thermal hydraulic behaviours.
The protein-protein interactions important for viral membrane fusion, penetration, replication, and intracellular transport involve a multitude of long-range water-mediated interactions that are separately inaccessible to direct experiment and even to accurate numerical simulations.
